This guy wakes up one morning to find a gorilla in his tree. 
He looks in the phone book for a gorilla removal service
until he finds one.

"Is it a boy or girl Gorilla?" the service guy asks.

"Boy", is the mans' response.

"Oh yeah, I can do it.  I'll be right there", the service
guy replies.

An hour later the service guy shows up with a stick, a
Chihuahua, a shotgun and a pair of hand cuffs.  He then
gives the man some instructions.

"Now, I'm going to climb this tree and poke the gorilla with
the stick until he falls. When he does, the trained
Chihuahua will bite the gorilla's balls off.  The gorilla
will then cross his hands to protect himself and allow you
to put the handcuffs on".

The man asks, "What do I do with the shotgun?"

"If I fall out of the tree before the gorilla,
shoot the dog."
