There is a family gathering, with all the generations around the table.
The teenagers put a Viagra tablet into Grandpa's drink.
After awhile, Grandpa excuses himself because he has to go to the bathroom.
When he returns, however, his trousers are wet all over THE FRONT
"What happened, Grandpa?" he is asked by his concerned children.
"Well," he answers, "I don't really know....
I had to go to the bathroom.... ....
So I took it out and started to pee, but then I saw that it wasn't mine, so I put it back!"
