Hunting Beaver
An 80-year old man walks into the doctor's office for his regular check-up.
The doctor says to him, "Ahh, Ted, how are you feeling?"
"Great," says the old man. "I have an 18-year old wife, and she's pregnant with my child."
The doctor gives a concerned look and says to Ted, "Ted, let me tell you a story. See, I have this hunter friend, and early one morning, he goes out hunting, but is in such a hurry that he grabs his umbrella instead of his gun. So, as he is hunting, he spots a beaver. He aims at the beaver with his umbrella and shoots at it. Bam! The beaver falls down dead."
"What?!" cries the old man. "Why, that's impossible! Someone else must have shot the beaver."
"Exactly," says the doctor.
