Homer: How much can I get for this?
[He hands the Comic Book Guy a mint condition Joe Dimaggio rookie card]
Comic Book Guy: Well, sir. I'm afraid your card is only worth...
[tips out the cash register]
Comic Book Guy: Everything I've got! Take it!
[he kisses the card]
Comic Book Guy: Oh no, I have smeared it with nacho fingers. I must deftly lick it off.
Marge: How did this happen? How did the Simpsons become the bottom rung of society?
Homer: I think it was when that cold snap killed off all the hobos.
