Inspired by some previous posts relating to unicycle injuries I thought I’d post mine.
This was the result of the attempt to perform the little known (but widely used) trick ‘unicyle to boot’! Sadly my head got in the way 
hmmm… I can’t say I’m familiar with that one… more details please!
I’m afraid that elaborating will make for a far less glamorous story
After a nice hack in the local park at lunch time, I was putting the Uni back in the car boot and forgot to duck!
Isn’t it crazy when you hurt yourself with your unicycle and you aren’t even riding it? I recall once, I was holding my unicycle, when suddenly I lost my balance and fell over, all without even getting on.
