There are two bats in a cave and one says to the other "I could do with some blood right now" the other said, "Me too but its almost sunrise". The first one said, "Wait here" he flies off and comes back with a mouth full of blood. The 2nd bat says, "Hey where'd ya get that blood from?" The other replies, "Ya see that tree over there?"
"Well I didn't"
The 2nd bat looks puzzled and says, "What’s that got to do with blood?"
The first one rolls his eyes and flies off.
