A man has a bear perched on the roof of his house. He has tried everything to get the bear off the house but nothing works. So finally he gives up and calls the bear exterminator.

The bear exterminator shows up in an old pickup with a huge cage in the back. After he surveys the situation he begins to unpack his truck. He takes out a wooden baseball bat, a shotgun, and a manegy old mean dog.

The homeowner inquires about how he is going to get that bear off the roof.

The bear exterminator replies, It is really quite simple. I am going to climb up on the roof with this bat. I am going to beat on that bear till I knock him off the roof. When he falls off the roof that dog is going to grab the bear by his testicles and rip and tear until the bear gets in the cage and I will lock the cage.

The homeowner is puzzled. He says I understand everything except what is this shotgun for?

The exterminator says just in case I get up there and the bear fights back and knocks me off the roof, grab the shotgun and SHOOT THE DOG!
