If I tell you, will you give me a quarter?
A new customer sees a sign in a bar that reads, "IITYWYGMAQ". In a puzzled voice he asks the barkeep the meaning of the sign. The barkeep replies, "If I tell you will you give me a quarter?" The customer gives the barkeep a quarter & waits. After a minute, the customer asks the barkeep again the meaning of the sign. The barkeep repeats his earlier statement & the customer is furious, but digs out another 25 cent piece & waited. The customer is livid now. This time the barkeep points to each letter as he says "If I tell you, will you give me a quarter?" The customer left blushing.
