Quote from Dorothy in Till Death Do We Volley
Trudy: Dorothy, what the hell is going on here? Dorothy: Revenge! It suddenly occurred to me. What if this was the ultimate practical joke? So I dragged it out of Jack, and the two of us cooked up this topper. Trudy: Jack, I can't believe you went along with this. Jack: So I got in bed with Dorothy. It was a joke! Dorothy: Don't even think it, Ma.
