Negligible set Puns

He was operating a late night train and fell asleep at the controls. He ended up failing to recognise a stop sign and as a result his train hit a person and killed them immediately. He was tried for manslaughter and sentenced to the electric chair. Just before being put in the chair, he was given the choice of final meal and chose a single banana, oddly. His time came and he was placed into the chair, the room vacated and then the switch was thrown.

But... Nothing. No sparks, no burning, nothing. They checked the machine and it was working fine, it just seemed not to harm him. The state law meant that, legally, his sentence had been carried out and he was free to go. He walked away a free man, and actually got another job as a train driver.

Sadly, almost exactly the same thing happened again. This time his negligence killed two kids playing around on the tracks when again he'd fallen asleep and failed to stop the train in time. Hauled before the courts again, he got exactly the same sentence - the electric chair. He was asked again for his final meal, chose two bananas this time, and his sentence was carried out again.

And yet again, he didn't die. In fact, he was entirely unharmed. The state law remained the same, so he was let out again, where - somehow - he got another job with another train company. I guess it was the only job he was trained for (pardon the pun). Anyway, this time he did much better and worked hard to stay awake during his late shifts. But sure enough, eventually he slipped back in to old habits and this time killed five people - a family trying to free their dog stuck in the tracks.

Once again he faced a jury, once again they found him guilty and a judge sentenced him to the electric chair. This time he asked for 5 bananas, but the guard was wiley - he has read about this man and how he always had bananas before his sentence was carried out, and so this time (with a grin, it's said) he brought the train driver 5 apples instead. The guilty man plead and begged for bananas, but the guard claimed it was an honest mistake but too late to change now.

The man was lead for a third time to the electric chair. His head was wetted, his arms strapped in, and the guard eyed him with something between wonder and fear. Finally the room was vacated and the switch thrown. Surely this time the machine would do its job? With the process finished, the guard ran back into the room, only to find the man still alive and looking entirely healthy. "I do
