Matthew Perry's character Chandler on the hit 90s sitcom 'Friends' was always calling people out, especially his roommate Joey. Many of Perry's iconic one-liners have been memorialized in fan videos online and Perry has even admitted to a favorite. During an appearance on Good Morning America, Perry said his favorite zinger was when he told Joey to "stop it with the q-tip when there's resistance." In an episode of the show Joey can't remember how old he was in 1990 and Perry makes the q-tip comment, alluding to the fact that Joey isn't the brightest bulb.
