Homer's Brain: Why is Mr. Burns being so nice to me?
Mr. Burns: And if you scratch my back, I'll scratch yours.
Homer's Brain: Wait a minute. Is he coming onto me?
Mr. Burns: I mean, if I should slip something into your pocket, what's the harm?
Homer's Brain: My God! He is coming onto me!
Mr. Burns: After all, negotiations make strange bedfellows. (chuckles, winks)
Homer's Brain: Aaaaaagh!
Homer: Sorry, Mr. Burns, but I don't go in for these backdoor shenanigans. Sure, I'm flattered, maybe even a little curious, but the answer is no!
