Does anyone else have an (almost) irrational hatred of someone they've never met, and know nothing about?

In one of the old BBC1 idents, there was some girls at a comedy 'gig' jumping up and down, there was some beardy weirdo in a tracksuit with a glowstick behind them. For some reason every time I saw this chump in the ad I got angry, and knew he would be my arch-nemesis. Who's yours?
