Three vampire bats live in a cave surrounded by three castles.
One night, the bats bet on who can drink the most blood.
The first bat comes home with blood dripping off his fangs.
He says:
“See that castle over there?
I drank the blood of three people.”
The second bat returns with blood around his mouth.
He says:
“See that castle over there?
I drank the blood of five people.”
The third bat comes back covered in blood.
He says:
“See that castle over there?”
The other bats nod.
“Well,” says the third bat:
“I didn’t.”
Cheers
