a note for posterity.. the comedian stephen wright should get some credit for the 'extra medium' bit. he's had a deadpan routine for years that has gone as such:
in reply to Perl Monks say the Darndest Things
" I love to go shopping. I love to freak out salespeople. They ask me if they can help me, and I say, 'Have you got anything I'd like?' Then they ask me what size I need, and I say, 'Extra medium.'"
another of his:
"I saw a sign at a gas station. It said 'help wanted'. There was another sign below it that said 'self service'. So I hired myself. Then I made myself the boss. I gave myself a raise. I paid myself. Then I quit."
