A Shaggy Dog Story and Generic Viagra.

A tired, scruffy old dog lay in the shade beneath a window. A fly buzzed around his head and he shifted in his sleep, restlessly. He could hear voices above him chatting and giggling and the static sound of sheets and skin on skin. He moved his tired old bones into a more comfortable position and noticed the voices becoming more excited.
"Yes, yes yes!" the man in the bedroom above was gasping excitedly. The dog realised that this was the happiest the man had sounded in a few months. Lately all the whispers had sounded disappointed and there had been discontented murmurings resonating around the room.
"Oh darling," the woman exclaimed, "That was wonderful!" He heard the sound of bodies pressed against each other and sheets rustling. Both the man and the woman sighed with pleasure and appeared to lie back on the bed.
"Oh, I was worried that this period of not being able to have sex would go on forever." The man said, "But I found a solution on the Internet, darling and decided it try it."
"What is it?" she asked and the dog heard a cardboard packet being passed across the room. "This," said the man, "Generic Viagra. I found a website that explained my symptoms of erectile dysfunction and it said that Generic Cialis or Generic Viagra would help me to get back on track so I decided to try it and I feel full of vitality and ready for anything." He was lazily stroking the woman's back and she moaned.
"You had better have another of these Generic Viagra," she laughed, "I have missed this and want more!"
"I don't need to, these last for ages," he said and threw the packet aside and scooped her into his arms.
What he didn't notice was that the packet had landed on the window sill and teetered slightly before dropping to the ground, right next to the old dog's leg. He sniffed them. He realised that it had been a while since he had entertained a lady friend and decided to see if he could share in some of this good luck. In a gulp, he swallowed the tablets, packet and all and sat around to wait and see what would happen.
Half an hour later, he wandered into the alley at the back of the house to see if the pug from next door was around and sure enough, there she was. He bounded up to her, had a sniff, as dogs are prone to doing and set about getting himself some of the action he had been listening to not half an hour before.

"Well," thought the shaggy dog, "you can't teach an old dog new tricks, but there is certainly life in this old dog!
