There sure seems to be a lot of 'I forgot to put my kickstand down." LOL
I used to have a buddy who would pull up to a stop light and forget to put
his feet down. I can't tell you how many times his girlfriend and I helped him upright it.
My most embarrasing moment:
Riding with a group of friends one night on our way to a party when one of the guys wants to stop by his store to pick up something. So we take the back roads thru town to miss the stop lights. I'm the last of 4 bikes. Turn a corner and gas it up a hill. This is on a Sporty with a 6" over springer and no brake. The front end comes up and dumps me off. But, being the smart guy that I am, I'm still hanging on to the bars. We, the bike and me, end up right in the middle of the street. Me on my stomach, the bike upside down balanced on the bars and the rear fender. There was a kid about 11-12 years old walking up the sidewalk. He sees the whole thing and says "That was pretty wild, can you do it again?"
After getting the bike back on it's wheels and confirming that, other than some spilled oil, slightly 'modified' handlebars, and a big scrape on the rear fender it was ready to take me to the hospital to get 10 stitches in my chin.
Never did make the party.
