Tarzan doesn't have a beard? night falls but day breaks? the third hand on a watch is called the second hand? lemon juice is made with artificial flavours, but dishwashing liquid is made with real lemon? you can buy an entire chess set in a pawnshop? pilots don't take crash courses? Roman paramedics don't refer to IVs as 4s? we can't imagine a world without hypothetical situations? there are self-help "groups"? you can get off a non-stop flight? with Barbie so popular, you still have to buy all her friends? peanut butter cookies are made of peanut butter, but Girl Guide cookies aren't made of ...? if space is a vacuum, nobody changes the bags? if swimming is so good for you, whales look the way they do? we sing "Take Me Out to the Ballgame" when we're already there? the time of day with the slowest traffic is called "rush hour"?
