Any Visions commercial on the Fan. Reminds me of this: (except they think it'll work)
Homer: Well, I really should discuss this with my wife.
Salesman: Your wife? (cracks an imaginary whip)
Homer: What, you think I'm going to buy a $20,000 truck just because you
make that noise?
Salesman: (cracks his whip again)
Homer: Okay, I'll take it.
