So a man and his father... A man and his father were at the man's house, when his dad notices a bottle on the table. He picks it up and asks, "Hey, whats up with this viagra stuff? Can I give it a try? The man replies with, "Eh, well, you really shouldn't..." -C'mon, just a little, I haven't gotten frisky in a while." -Uh, whatever. Try it... -Great, thanks. If it works well, i'll leave 10$ by your computer in the morning. So in the morning, when the man woke up, he noticed 20$ right next to his computer. He tells his dad, "Dad, I thought you said you'd leave only 10$ if the viagra worked fine." "I did. The other 10$ is from your mother"
