A customer at Paul’s Gourmet Grocery
marveled at the proprietor's quick wit and intelligence.
"Tell me, Paul, what makes you so smart?"
"I wouldn't share my secret with just
anyone," Paul 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 $5 apiece," says Paul.
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," says Paul. The
customer goes home with 20 more fish heads. Two weeks
later he's back, and this time he's really angry.
"Hey, Paul," he says. "You're selling me
fish heads for $5 apiece when I can buy the whole fish
for $3. You're ripping me off!"
"You see?" says Paul. "You're getting
smarter already!"
