A lady walks into a bakery and sees a shirtless baker behind the counter making Danishes. He slaps the dough against his breasts to create indentations, then he spoons in the jelly.
Shocked, the lady cups her cheeks in her hands and exclaims, "Oh, my! Sir, that's disgusting!"
To which the baker replies, "Lady, if you think that's bad, you don't wanna be here when we make the bagels."
