I Remember Him from High school

Imagine walking down the street minding your own business when the police stop you, say you match the description of someone who just committed a serious crime, put you in handcuffs, and present you to a witness in the field.  Before you could blink an eye, you have been misidentified and find yourself in a jail cell.  The real kicker is, the witness who identified you actually went to high school with you years ago but does not remember you from those days.  Rather, he figures that the reason you look familiar is because you’re the culprit.
