Ned: What a great pot party!

Maude: Wasn't it, man?

Ned: Now for a regular cigarette to make the night complete.

[lights one, takes a drag, and coughs] Oh, man that's good.

Maude: Mad Dog, I've been thinking. Maybe we should get another smoke detector in case that one trips out on us.

Ned: [laughs] Why bother, baby. One smoke detector's enough for Mad Dog. Now let's hit the sack.

[they both lie down in bed. In short order, Ned -- er-- Mad Dog's cigarette sets his pants aflame]

Whoa, check it out! Mad Dog's on fire!

Maude: Stop, drop, and roll, man!

Ned: Ha, ha, ha, that's for clydes, baby. A little fire can't hurt you.
