I was a little tired, and when I tried to wave at them to show my approval of their world class prank, I was only able to muster up one finger.
Normally my 93 year old father is nothing but a gentleman, but he had us rolling on the floor recently when he responded to some political jibes at a family dinner with a back-handed, finger wiggling wave. He said: "You know what this is?" No, Dad, what? "Five of these"..... (figure it out....) If you weren't so tired, you could have done the same.
