When Viagra first came out my wife and I decided to give it a go to see what all the fuss was about.
I popped the pill and waited the 15 minutes and then it was on for young and old.
We timed the performance to the minute and it all finally subsided at 3 hours and 17 minutes.
I asked the missus what she thought and she simply stated that she couldn't understand what all the hype was about for an extra 17 minutes...
