The Strongbox Season 9, Episode 14

George

So, what's in the cooler? (flips open the lid)

Kramer

Oh. Well, would you look at that. (puts a gun-shaped hand to his head and goes 'Pop') I guess I forgot to lock it.

Jerry

You mean it was open? We desecrated a pet cemetery for nothing?

Kramer

Well, this is one for the books, huh, Jerry?... Reeeally one for the books!
