Yep, done ALL those.
I'll add one; at a large gathering of Gearheads, Hot August Nights at a major casino in Reno. I parked in a throng of bikes, most HD's.
Came back out, everybody there is revving motors and there's a huge gathering of people just admiring cars and bikes I mount up give it a good rev to leave and LAUNCHED the bike at a 45 degree angle because I left the wheel lock on. Bike shoots in-between two 20k dressers and slams down onto the pavement right in front of the valet where everybody's waiting for their cars. Leaving me standing there to take a bow to my adoring fans.
