Park Bench

[Bad Karma]

Grandpa and Little Johnny are sitting on a bench in the park. Johnny asked, "Grandpa are you going to take that new Viagra?"
Grandpa looks at him and says, "No Johnny, I will not."
"But Grandpa, why?" asks little Johnny.
Grandpa replies, "Because there is no sense in putting lead in your pencil if you have no one to write to."
