Three dogs, a Doberman, a Boxer, and a Labrador are sitting in the waiting room at the vet's office when they strike up a conversation.
The Doberman turns to the Boxer and says, "So why are you here?"
The Boxer replies, "I'm a pisser. I piss on everything - the sofa, the cat, the kid, but the final straw was last night, when I pissed in the middle of my owner's bed."
The Doberman says, "So what is the vet going to do?"
"Lethal injection, at 3:00 pm." came the reply from the sad Boxer.
The Doberman then turns to the Labrador and asks, "Why are you here?"
The Lab says, "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. 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 Doberman inquired.
"Lethal injection, at 3:30 pm." the dejected Labrador said.
The Labrador then turns to the Doberman and asks what he's at the vet's office for.
"I'm a humper," the Doberman says. "I'll hump anything. I'll hump the cat, a pillow, the table, fire hydrants, whatever. I want to hump everything I see. Yesterday, my owner had just gotten 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 Boxer and Labrador exchange a sad glance and asked,
"So, What time is your lethal injection.??
"No, no," the Doberman says,
"I'm here to get my nails clipped."
