Solution for #23

The native chief asked him, "What is the third baseman's name in the Abbott and Costello routine 'Who's on First'?" The man, who had no idea, said "I don't know," the correct answer. However, he was a big smart aleck, so if he had known the answer he would have pointed out that "What" was the second baseman's name. The chief, being quite humorless, would have executed him on the spot.
