A man wakes up one morning to find a bear on his roof. So he looks in the yellow pages and sure enough, theres an ad for Bear Removers. He calls the number, and the bear remover says hell be over in 30 minutes.
The bear remover arrives and gets out of his van. Hes got a ladder, a baseball bat, a shotgun and a mean old pit bull.
"What are you going to do?" the bewildered homeowner asks.
"Im going to put this ladder up against the roof, then Im 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."
"Huh," the homeowner says. "But whats the shotgun for?"
"Well," the professional says as hands the shotgun to the homeowner, "if the bear knocks me off the roof, you shoot the dog," he said.
