Meg's Vulgar Skills

In "Girl, Internetted", Peter asks Meg for a skill they could use to make her internet famous, she reveals she does something so vulgar and horrible covered by long bleeps (even on the DVD release!) that Peter almost bursted into tears. When she mentions shuffling a deck of cards in an equally appalling manner, he decides to remove her bedroom door so that she doesn't try anything like that again.
