Prisoner Question Machine: Please an-swer yes or no: Do you have a-ny chil-dren?
[the men press their buttons, but the Professor looks puzzled]
Prisoner Question Machine: Someone hasn't pressed his but-ton! Someone hasn't pressed his but-ton!
Prison Guard: What's the idea here, buddy?
Fred the Professor: These machines are silly!
Prison Guard: What's the big deal? You just press "yes" or "no".
Fred the Professor: Yes, but suppose my answer is "maybe"...
