Lois: Hal, I don't know why you have such a hard time making decisions.
[flashback:]
Hal's Mother: Hal, sweetie. You have to decide. For your birthday, do you want a petting zoo or a clown?
Young Hal: Both?
[flashback to a clown struggling to get a snake off his neck]
[present:]
Hal: Who knows? Probably no reason. You might as well ask me why I'm afraid of clowns and snakes.
