A customer at the Tesco’s fresh fish counter marvelled at the
fishmonger’s quick wit and intelligence.
“Tell me, Fishmonger, what makes you so brainy?”
“I wouldn’t share my secret with just anyone,” the fishmonger replies,
lowering his voice so the other shoppers won’t hear. “But since you’re a
good and faithful customer, I’ll let you in on it. Fish heads. You eat
enough of them, you’ll be positively brilliant.”
“You sell them here?” the customer asks.
“Only 2 a piece,” he says
The customer buys three. A week later, he’s back in the store
complaining that the fish heads were disgusting and he isn’t any smarter.
“You didn’t eat enough, ” said the fishmonger. The customer goes home
with 20 more fish heads. Two weeks later, he’s back and this time he’s
“Hey you,” he says, “You’re selling me fish heads for 2 a piece when I
can buy the whole fish for a 1. You’re ripping me off!”
“You see?” said the Fishmonger. “You’re more intelligent already.”
