God Chats to Adam Joke

So God calls to Adam and says, "Adam, I have some good news and some bad news.

What do you want to hear first?"

Adam replies, "The good news”.

God answers, "Well, the good news is I gave you a penis and a brain."

Then Adam says, "OK, so what's the bad news?"

And God says, "I only gave you enough blood to operate one at time”.
