Four Men Go Hunting...

They split up into pairs and hunt in different areas. Later, two of the hunters come across the other pair to find one hunter bent over a tree stump with the other fucking him in the ass.

Shocked, the other hunters yell, "What the hell are you doing?"

The hunter who is doing the fucking says, "He had a heart attack."

To which the other hunters reply, "Well then you should have given him mouth-to-mouth resuscitation!"

"How do you think this got started?!" he replies.
