That reminds me:

Flying my Hippo Tippo pattern Plane for an Airshow in Vacaville (20 years ago) while riding my unicycle and the pedal broke.

...NOT a GOOD THING.

The rest of the story: I was doing a split-S and as the plane flew past me I let the unicycle go (to the ground - argh@^@&^#&#&&) as my thumb slackened on the stick and the airplane bounced off the ground breaking the prop and an aileron pushrod back into the air. I immediately flipped the retract switch turned around and landed deadstick without incident.
