Two bats are hanging in their cave. One turns to the other and says, "Oh,
I'm really thirsty for some fresh blood."
The other bat is amazed and says, "Well, it’s a bit late. Daylight is almost
here, and we can't be exposed to any light - you know we'll die." "Yeah, I
know," says the first bat, "but I'm really starving for it."
So he flies out of the cave and returns five minutes later with blood
dripping from his mouth.
"You lucky thing. Where'd you find blood that quick?" asked the second bat.
"You see that tree over there in the distance?" mumbled the bat, his mouth
full of blood.
"Yeah, I think I do!"
"Well, I didn't."
