There's a burger bar close to me that always has on their sign as a joke, "free beer tomorrow." I went in one night and asked for a free beer, and the waitress smiled and said "Sorry, that's tomorrow."

I said "But the sign was up yesterday. Today is yesterday's tomorrow.  And if you honor it, you could get two days' worth of tips from me today."

I got my free beer, and she got a really good tip.
