David Letterman says he was offered a cameo in the Spider-Man movie. “Yes, I have had offers, but what I get is people saying, What would you like to do, and I say, I did what I’d like to do.

I don’t think there is a device that’s invented that is capable of measuring the amount of time it took for me to hang up the phone.
