In which episode does a stewardess ask Stewie if he'd like a hot towel and he says yes and pulls down his pants? I saw this clip on a commercial and cant find the episode. Thanks.

episode 22 - i think series 8 - if not series 7 ! its the epsisode wheb Stewie goes to England to the BBC to find his 가장 좋아하는 kinds program ( piss take of teletubbies) -- funny one !
