i worked with this guy once who was obsessed with early 90's aerosmith music. this was in 2003. at staff parties he would insist we put on some aerosmith, a suggestion he could always back up because the albums were always in his car. he had an idiot savant's memory for phone numbers, birthdates, and the years when films were released. you don't want to hang out with guys like this, but you do want to work with them. managers should be required to hire at least one.
