Luck striking like lightning, he found himself invited to "Who Wants to Be a Millionaire."
Many questions later and he is doing rather well. He is at the final question for a million dollars, he has only one lifeline left - phone a friend.
The question comes: "Which bird does not make a nest?
A) a Sparrow, B) a Swallow, C) a Blackbird or D) a Cuckoo
Bobby doesn't know so he calls his friend Billy.
Billy answers 'by Christ Bobby, it's a cuckoo - 100%.'
Bobby goes with the advice his friend gave him and indeed that answer wins the million dollars and he is so very happy.
Afterward, Bobby rings Billy and asks him 'How the heck did you know that? You're no bird expert!'
'Well Bobby you idiot," Said Billy, "What an easy question, He lives in a bloody clock, right?"
