7. Barry - High Fidelity
Back before Jack Black was a household name, he grabbed everyone's attention with this supporting role in High Fidelity. He plays one of John Cusack's employees at the record shop, and he is perfection. You can try to tell me you wouldn't want to be working with this guy, but you'd be lying. He's a music snob of the highest order, willing to verbally abuse customers if they come in looking for "I Just Called to Say I Love You". But really, isn't that what you want out of a record store clerk? Someone who's going to sneer and berate you for whining about the fact that Echo and the Bunnymen broke up?
