It's not what you're asking for but here I go.
Yes. It was completely unintentional and almost killed me.
It was when I was still learning and getting used to the clutch/throttle.
I was pulling away from a stop sign and accidently let out the clutch too early, but instead of the bike stalling, I grabbed a handful of throttle and before I knew it the bike was completely vertical and I was 100 feet past the intersection.
I was barely hanging on and I couldn't see anything, and thankfully I figured I should probably pull in the clutch, and when I slammed down I saw a parked car right infront of me so I managed to swerve and brake without hitting it or anything else.
