I don't think you would necessarily "look stupid" for not knowing them. It's all part of the process MBASS. :) When my wife, new baby son and I lived in SLC, "an agent" came over and told us, "No Jennifer Azi (WMBA superstar-I guess) is moving in next door. She is very private and doesn't want people asking for her autograph." I said, "First of all, I have no clue who that is and secondly, if anyone is going to be asking for an autograph, it will be here asking for my son's."
