"I don't know what you rolled in, but it sure smells good."

[gcruse]

And this one: The male dog shows up at his date's house with flowers in paw. The female says, "I don't what you rolled in, but it sure smells good."

Actually, it's even funnier than that.  The dog is at his date's door, holding in his paw some flowers.  He says, "Gosh, you look pretty, Daisy.  And whatever you rolled around in sure does stink!"
