A guy really wants to fuck his wife in the ass. But no matter what he tries she always says no. So he goes to a sex therapist for some advice. The therapist says, "There's one sure-fire solution to your problem. There's a very special herb that only grows in the Amazon. It's very hard to find, but if you go there and find it, it'll be well worth it, because it'll solve your problem."
So for ten years the guy visits the Amazon. Each year the journey is fraught with danger, including being caught by cannibals and almost dying of malaria. Finally, after years of searching, he finds the herb and brings it back to the doctor. The doc tells him: "Leave it with me, and I'll prepare it. Come back tomorrow."
The next day when he returns the doctor hands him a little bottle filled with a mysterious green liquid. The guys asks: "Okay, how do I use it, Doc?"
The doctor says, "It's easy. You put the bottle on your wife's night stand. Then you say, 'Honey, would you grab that little bottle for me?' And when she turns around and bends over to grab it, boom!, you fuck her in the ass."
Three Labrador retrievers - chocolate, yellow, and black - are in the waiting room at the vet's office when they strike up a conversation.
The black lab turns to the chocolate and says, "So why are you here?" The chocolate lab replies, "I'm a pisser. I piss on everything – the sofa, the drapes, 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 says, "So what is the vet going to do?" "Gonna give me Prozac," came the reply from the chocolate lab. "All the vets are prescribing it. It works for everything."
The black lab then turns to the yellow lab and asks, "Why are you here?" The yellow 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. 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 Prozac for me too," the dejected yellow lab said.
Then the yellow lab turns to the black lab and asks what he's at the vet's office for. "I'm a humper," the black lab 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 over to dry her toes, and I just couldn't help myself I hopped on her back and started humping away."
The yellow and chocolate labs exchange a sad glance and say, "So, Prozac for you too, huh?"
The black lab says, ‘Nah... just here to get my nails clipped."
