A biology student doing his thesis on
wasps is walking down the street when he passes a
record store.
In the window he sees a
record called "
wasps of the world, and the sounds they make". Intrigued, he walks into the store. He says to the shopkeeper "I'll have that
wasp record in the window please. I've been listening to so many
wasps, I'll probably be able to know each and every one of them."
He smiles smugly as the shopkeeper feigns interest. The student pays and leaves. When he gets home he puts the
record on.
"Bbzzzzzzzzz" it goes, but the man is stumped, he doesn't know what type of
wasp this is! He waits for the next track.
"Bbbbzzzzzzzzzzzz" and again, he can't identify which species of
wasp this is!
It gets to the fifth track and he breaks down. He can't identify a single
wasp yet he thought he was already an expert on the subject! He calls his professor round to the house to help, when he arrives he explains to him:
"I thought I was an expert by now, but I can't identify a single
wasp on this whole
record!" He says, almost in tears.
The old professor ponders for a minute as he looks at the
record. "Ah, I know what the problem is!" He says.
"What? what is it?!"
"You've got it on the B-side!"
