> "Bear Removers."
>
> He calls the number, and the bear remover says he'll be over in 30
> minutes. The bear remover arrives, and gets out of his van. He's got
> a ladder, a baseball bat, a shotgun and a mean old pit bull.
>
> "What are you going to do," the homeowner asks?
>
> "I'm going to put this ladder up against the roof, then I'm going to
> go up there and knock the bear off the roof with this baseball bat.
> When the bear falls off, the pit bull is trained to grab his
> testicles and not let go. The bear will then be subdued enough for
> me to put him in the cage in the back of the van.."
>
> He hands the shotgun to the homeowner. "What's the shotgun for?"
> asks the homeowner.
>
> "If the bear knocks me off the roof, shoot the dog."
