I'm a master of the prank phone call and have goten most people i know. One of the best was when i phoned a girl, who we all tease about looking like dory from finding nemo, and asked her if she could fill in for dory in our production of finding nemo on ice. Shes so stupid i had her asking for directions to the "ice rink" it was soo good, i had the phone on loud speaker and all the boys on the shinty bus were in tears. I liked it. I guess the ultimate one would be to get some one and "back sack and crack" them as they slept.
