Walt clears out an entire house full of rowdy teenagers by standing on a chair and yelling "EVERYBODY OUT! I'M AN ORTHODONTIST AND I'M NOT AFRAID TO PROVE IT!"
Walt complains to Jeremy about how songs nowadays are full of sex and drugs and it wasn't like that back when he was a kid. Jeremy instantly rattles off a long list of 60's era songs, considered classics, which are full of sex and drugs references. Even Connie says, "Score one for the teenager."
