Groucho Marx popularized this old joke in his 1950s TV show, ‘You Bet Your Life.’ It was asked as consolation question to those contestants who won no money during the regular series of quiz questions. Other consolation questions asked included, “When did the War of 1812 start?” “How long do you cook a three-minute egg?” and “What color is an orange? In actuality, no one is buried in Grant’s tomb but the remains of Grant and his wife are contained therein. However, the correct answer on Groucho’s show was, of course, Grant.

I agree that No one is buried in Grant’s tomb as tombs are above ground and therefore no one is actually buried in it!
