their used to be a phoneline that was related to one of these reality shows, and when you rang the line, the idea was to dial the number of the person you wanted to prank, then they would call the number, and the judge from the show would ask who ever answers the phone to sing

so I did this to someone I used to know and she's like oh my god, oh my god, I am going on a reality show.. simon cowel liked my singing!, and for weeks I kept it up.. yeah yeah, well i'm not surprised it's pretty good. you have a great voice

eventually though I did tell her what had happened and she's like oh, so i'm not going on the show?

tricked her again the following year by making some fake tickets to an actual concert of a band she liked playing that weekend

OOO pranks are fun!
