Maurice and his wife Esther visit the town carnival every year and every year Maurice always says: "Esther, I'd like to fly in that helicopter". Esther always replies: "I know Maurice, but the ride costs 50 quid, and 50 quid is 50 quid." One year Maurice pleads, "Esther, I'm 85, if I don't fly this year, I might never get another chance." "Maurice, the helicopter is 50 quid, and 50 quid is 50 quid," replies Esther. The pilot overhears and makes them an offer, "I'll take both of you up," he starts, "and if you don't say a word throughout, I won't charge you. One word though, and it's 50 quid." The couple agree. The pilot does all kinds of fancy moves, but not a word is spoken. He does his daredevil routine over and over again, but still nothing. When they land the pilot turns to Maurice and says: "I did everything to get you to yell out, but you didn't. I'm impressed!" Maurice smiles coyly, then says: "Actually, I nearly said something when Esther fell out, but you know, 50 quid is 50 quid."
