Why is Adolf juggling on a Giraffe, any context 
It was a cutaway in an episode of Family Guy.
I was just looking at ‘youtube’.
Searching for a ‘free’ 
(ahem) version of “Pitch Perfect”.
I saw this…
Has anybody watched this film and does anyone actually ride this unicycle?
Alucard
The curly-haired dude on the left rides it. His name is actually “unicycle”. He doesn’t ride it much in the film, but he does.
Thanks idlux 
Jennifer’s Body
I saw Jennifer’s Body recently. In the corner of Chip’s room, a unicycle is visible in several scenes. No reference is ever made to it.
My personal favorite unicycle in a movie is a clown from the red triangle gang shooting a tommy gun while riding a unicycle… only to have a UPD on the batmobile: https://www.youtube.com/watch?v=TUFHuYMG-nw
There’s a giraffe unicycle in the masquerade ball scene in van helsing. And I noticed a uni in one of the scenes in the How the Grinch stole Christmas with Jim Carey last time I was watching it.
I was surprised to see a uni (maybe a 26) in the background of a documentary about a pro skater recovery after an ankle injury.
Look at 6:08. Unfortunately, it is less than 2 seconds…
Well spotted, it’s not on screen for a long time, and it’s far in the background!
I felt like I had OCD when I stopped to look closer
Thanks for confirming 
Sidd, I can be as OCD as you… if not more!
A friend sent me a short doc/ad about a new camera rig allowing for cool ways of filming. I was surprised to see a uni at 1"17, and then again at 1"40 - this time for a whole 10 seconds! Same as your skate video, no one rides it…
Nice…
You forgot a quick appearance of 1.5 seconds at 1:28.
Ok, I have to take my pills now… :D:D
The Grinch
I remember seeing a unicycle in the backround on the grinch. From what I can remember he was bad at riding it.
I’ve got it on DVD somewhere, I’ll find it and send a screenshot of it.
In the animated movie Smallfoot at the 50:30 point there is mountain unicycling on an ice wheel. Cool. Double cool.
In the movie, “Airplane!” , a uni rides by toward the end when the emergency crews are headed for the runway after an emergency landing.
