Winner! 
I have definitely blamed it on weight shaving.
Where’s Your Other Wheel? Summary
Summary of answers to WYOW
The guy behind me picked it already up for me
I’ll try and remember to use it next time
If I got a quid for every time someone said that to me.
here it is…and show little airplane wheel around neck
I’m doing a wheelie, without the other wheel
On my bicycle
What’s the other wheel for?
How did you know I had another unicycle
You just need to drink more, then you will see it
This bike was on sale for half-off
This was a bike shop error in my favor
one wheel is all you need
one person on wheel
On my other unicycle
I got rid of the training wheel
I got old and worn out…like that joke
I needed a real challenge! If they’re on a bike, add, "what’s your excuse!?
It was stolen, but it’s ok, they left me the best half
It had a puncture
When do you plan on getting rid of your training wheel?
What do you mean ,where’s my other wheel ?, OMG someone’s stolen my other wheel AAaaaarrrrrggggg
I took the off the training wheel
The other 40 (or so) are in my garage
Safe and sound in the car
Budget cuts.
Don’t need a training wheel
What other wheel?
This is the other wheel
It was too heavy
It’s this damn recession
The world is my other wheel.
What! Where would I put another wheel on this thing
My favorite from this string: Left it at your Moms House!
thats the one i use 99% of the time. the only other one i use is ask obama
Not exactly sure how well they translate - you will let me know:
- Hey man, you wanna pull me a leg or what?
- On my little brother’s tricycle!
- Goes to seed in kindergarten!
- In the sky!
The first and third make no sense to me 
So I’d say not a good translation on those two, but the kid’s tricycle works 
I also get. DO A WHEELIE! Or DO A TRICK. Anybody have responses to those?
i reply DO A CARTWHEEL. Or YOU DO A TRICK. or HOWABOUT A TREAT
Or sarcastically- I HAVENT HEARD THAT ONE BEFORE to let them know their cleverness was unoriginal
People immediately think youre there for their entertainment. I contantly hear WYOW and people singing the circus tune, Da da dadadada da Da da
Ive also feinted not knowing my other wheel was gone and looked surprised when i turn around.
I cycle on the beach in orange county, ca and there are LOTS of people and have gotten group applause and many positive comments and WOOOOOO!!!
My favorite by two kids
“look a unicycle”
“ya, and its 4 wheel drive!!!”
(I have a larry 3.8) hahaha
The first one is easy - “I already am” has got a chuckle whenever I’ve used it - the obvious alternative is doing a rolling hop. More often than not when asked to do a trick I stop and do hopping 180s or hopping on and off stuff, given that’s the most impressive thing I can reliably do. Though I suppose it depends whether they ask or demand, how nice they are and how often you get it - mostly I perform for kids who are impressed by my basic skills. You could always reply “I already am” for that one too 
Actually a good reply to the original would be a comment I got from somebody last week - “They’ll nick anything round here”.
when i see bike riders i say “i like you 2 wheel unicycle”
That’s a good one. A little simpler than “the government gave it to someone who didn’t have a wheel”…
After a long time of not riding, I have done four rides in the past week. Have gotten a WYOW, or close variation, every time. The line that came to my mind is one I think was on someone’s sig line, “My other wheel is in your mind” so I replied:
“In your mind”
The first guy I said that to paused, then said with a smile, and a bit of an epiphany, “You’ve heard that before!”
Two of us were out last Saturday morning, my partner replied: “We’re a tandem”.
I’m not good enough to ride in the street yet, but I do have a history of doing weird things.
My usual response when people make smartassed comments is usually “where’s your sense of adventure?”.
It’ll be a great day when I can say this to a stranger while riding my uni.
Give 'em to me in German and we’ll see if we can translate #1 and #3 better.
– UniT
I normally respond with the good ol’ fashion “F#CK YOU!” come back.
I’m kidding by the way.
I also like “This is the other wheel” It’s makes them think.
In south Wales (UK), the varient of this we get is “Who nicked your wheel mate”?
Or a couple of times a month “Go on mate fall of”, usually liberally peppered with expletives. I once rode on a country lane, that skirted a sports field full of teenagers of the unsavoury kind. I got some nice comments but mostly verbal abuse before shortly afterwards two glass bottles whistled past my face and smashed on the wall. That will teach me for riding near one of the worst council estates in the south Wales valleys.
Wales is a great place, very screening, mountainous lots of neat places for Muni lovers, and general the people are very nice. There are just one or two pockets of badness, or as us Brits would say Chavyness.
I like the answer posted earlier, “On my other unicycle.”
I have never gotten asked this question, I rarely ride in public though. Most people have just ignored it, or a few people say it’s awesome. I don’t think it would bother me though (although I’m sure a lot of you have been riding long enough to get extremely tired of it). Mean or nasty comments would bother me though. =P
Can’t believe people threw bottles at you scottie, that would scare the crap out of me!
I was in South Wales (Porthcawl) when I got my “They’ll nick anything round here” comment - but I took that as friendly rather than smartarse.
I doubt they get it but it’s funny to me.
