Lois: You know, I have to admit, part of me wishes we could just stay this happy forever.
Hal: Can we, Malcolm? Can we?
Malcolm: Not really. [lisps] I mean, most of these drugs wear off after four or five hours.
Lois: Malcolm, why are you lisping?
Malcolm: I pierced my tongue. I've been hiding it because I knew you'd go psycho.
Lois: I'll show you psycho. When we get home, I'm going to pull that thing out with a pair of pliers.
Malcolm: Sounds fair.
