An alligator goes to the vet one afternoon. "What can I do ya for?" the veterinarian asks.

"Well doc," says the gator, "I haven't been my normal self for weeks. I used to be able to swim for hours and chase prey. Now, I can barely swim twenty feet and I haven't caught a single meal in days. Everything seems off."

"I see...I see." said the veterinarian. "I think I've got a cure for you."
The vet disappears into the back of the clinic and comes back with a bottle of pills. He hands them to the alligator, who reads the perscription.

"Viagra?!?" the alligator yells, confused. "What the hell doc?"

The veterinarian replies, "Its obvious to me you're suffering from a reptile dysfunction."
