Big, Small - It's All Relative

A local pizza parlor was offering free drinks with your pizza order on Sunday, so we stopped by after church for some pizza. I told the teenager, who looked like he was actually happy to be there, that I wanted a large Coke. He had to sadly tell me that only the small drinks are free. Since his fun-loving attitude was infecting my own mood, I said, "OK, then I'll have three small drinks in a large glass!" He grabbed a large glass, filled up a small glass three times and emptied it into the large glass, and handed it to me saying, "Here you go, sir - three free small drinks." Gotta love those creative teenagers.
