I was 14 years old and was riding my bicycle back to school from lunch at home.
Turn down an alley and a fellow (later found out he was 22 and had been in jail twice already) jumps out from behind a dumpster, grabs the handlebars and asks if he can have my bicycle.
Um, no (insert innocent kid trying to help) but I can double you to wherever you want to go.
He throws me off of the bike and rides off.
I run into the back door of the store, pick up the phone and call dad.
Dad drives like a maniac and gets there within five minutes.
Takes me to police sub-station.
We sit there processing the paperwork.
Cop asks me for a description of the bike, etc.
I happen to look out the window, and the criminal is riding my bike down the street in front of the police sub-station.
Cop calls him over. (At this point, the guy is thinking there is NO WAY that they could know I stold this bike less than 20 minutes ago.)
Motions for me to come out of the building.
I come out, the thief sees me and the color drains from his face.
Cop asks me to unlock the combination lock hanging under the seat.
I unlock the lock (establishing the bike is, in fact, mine).
Thief goes to jail for the third time before his 24th birthday.
True story.
