TGIF!!!! Joke of the day

Here's a joke my buddy sent me to cap off the week.  Everyone have a great weekend!!!!

Three  Labrador retrievers -- one brown,  one
yellow and one black were sitting in the waiting
room at the vet's  surgery when they struck up a
conversation.

The black lab turned to the brown  and said, "So why are
you here?" The brown lab replied, "I'm a pisser. I piss  on everything
--the sofa, the curtains, the cat, the kids. But the final  straw was last
night when I pissed in the middle of my owner's bed."

The  black lab said, "So what is the vet going to do?"

"Gonna cut my nuts off,"  came the reply from
the brown lab. "They reckon it'll calm me down."

The  black lab then turned to the yellow lab and asked, "Why are you here?"

The  yellow lab said, "I'm a digger. I dig under fences, dig up flowers and trees, I dig just for
the hell of it. When I'm inside, I dig up the carpets. But I  went over
the line last night when I dug a great big hole in my owner's  couch.

"So what are they going to do to you?" the black lab inquired. "Looks  like I'm
losing my nuts too." the dejected yellow lab said.

The yellow lab then turned to the black lab and asked, "Why are you here?"

"I'm a humper," the black lab said. "I'll hump anything. I'll hump the cat, a pillow,  the
table, postboxes, whatever. I want to hump everything I see. Yesterday,
my owner had just got out of the shower and was bending down to dry her
toes, and I just couldn't help myself. I hopped on her back and
started humping away".

The yellow and brown labs exchanged a sad glance and
said, "So, nuts off for you too, huh?"

The black lab said, "No, I'm here to get
my nails clipped."
