"The Gorilla.......................................!" joke

This guys 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".
An hour later the service guy shows up with a stick, a Chihuahua, a
shotgun
and a pair of handcuffs. 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.
The gorilla will then cross his hands to protect himself which will
allow
you to put the handcuffs on' im".
The man asks "What do I do with the shotgun?"
"If I fall out of the tree before the gorilla, shoot the dog"
