Dilbert reaches for a modem in a computer store. A man says, "No, you fool. That modem will never fit your need." Dilbert reads the box and thinks, "The specs look okay." The man yells, "You're an idiot compared to me! Put that down! It's the wrong interface! The WRONG interface!!!" As Dilbert hands the modem to a salesclerk at the cash register, the man clutches Dilbert's shirt and growls. Dilbert asks the clerk, "Is he on commission?" She answers, "Yeah, he pays us a dollar a customer."
