how to ruin someone's date

i tried it once as a prank at school with my friends and it worked. we set up this guy and girl on a date but told them each that the other person has a slight hearing problem so they need to talk at least 10% louder than usual to be heard. end result? they hated having met each other. the funniest part though was that each one believed in the end that the other person had a hearing problem when that was not the case. when the guy wanted to join the school choir she was so against this on the grounds he couldn't hear a damn thing..lol
