Yup.. my 9th grade science teacher would always tell jokes he knew where bad. He would prep us weeks in advance.. "Oh yeah it's coming.. the worst joke of the year".. here it is:

The Conductor

Once there was a bus conductor. On one particular day, one old woman tries getting into the bus, but the conductor does not stop the bus. She falls down and dies. He is tried in the court, found guilty and sentenced to capital punishment. He is taken to the electric chair cell.

In that room, there is one electric chair in the middle and a banana peal in one corner. He is strapped to the electric chair and high voltage current is passed. He does not die. The authorities release him. He goes back to work. He sees another old woman trying to get in to the bus; does not stop the bus. She too dies. He is tried and convicted. They take him to the same electric chair. The room, this time also, has a banana peal in one corner and the electric chair in the middle. Current is passed; he manages to survive. Perplexed the authorities release him.

He goes back to work. This time he sees an old man getting into the bus. This time he stops the bus; still the old man falls down and dies. The conductor is tried in the court and convicted (due to his earlier follies). This time also they take him to the same room with the electric chair in the middle and banana peal in a corner. This time when the high voltage current is passed, he succumbs to that and dies. Why does he escape the first couple of times?

The first couple of times, he did not stop the bus, he was a BAD CONDUCTOR. So current couldn't pass through him and he didn't die!! The third time, he stopped the bus.. he was a GOOD CONDUCTOR. So the current passed through him and he falls dead.
