Quote from Mandy in the episode Todd's Mom
Beth: [laughing awkwardly] So, 19... Mandy: Yeah, he's- he's very mature for his age. Beth: I'm sure. Mandy: And, you know, most days I-I don't even think about it. Beth: And why would you? Mandy: He's a good father and a hard worker. Beth: I bet the sex is amazing. Mandy: Oh, well, he does bring a certain youthful energy to the party. Beth: Do tell. Mandy: I think I've told enough.
