An engineer decides he wants to make some easy money, so he opens a “medical clinic” in an old corner store. His sign says:
“We can cure anything for $500. If we can’t, you get $1000.”
A brain surgeon sees the sign and thinks he’ll outsmart the engineer.
First visit:
“I’ve lost my sense of taste.”
The engineer calls, “Nurse, bottle 273!”
The surgeon sips it, spits it out: “That’s pee!”
“Great—you can taste again. $500, please.”
Second visit:
“My memory is failing.”
“Bottle 273!”
“That’s pee! You gave me that yesterday!”
“Your memory’s fine. $500.”
Third visit:
“I can’t see anything.”
The engineer sighs. “I can’t cure blindness. Here’s your $1000.”
He hands the surgeon a $20 bill.
“Hey! This is only twenty!”
“Perfect—you can see again. $500, please.”
