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".©OFFICEJOKES.NET

The first one said, "Wait here" he flies off and comes back with a mouth full of blood.©OFFICEJOKES.NET

The 2nd bat says, "Hey where'd ya get that blood from?" The other replies, "Ya see that tree over there?"©OFFICEJOKES.NET

"Yeah"©OFFICEJOKES.NET

"Well I didn't"©OFFICEJOKES.NET

The 2nd bat looks puzzled and says, "Whatand#37413;and#27290; that got to do with blood?"©OFFICEJOKES.NET

The first one rolls his eyes and flies off.
