Derailment jokes

My boss yelled at me the other day, “You’ve got to be the worst train driver in history. How many trains did you derail last year?”

I said, “Can’t say for sure, it’s so hard to keep track!”

The first trains were often derailed. They had a bad track record.

Boss: Why are you so bad at driving trains? How many have you derailed this year?

Me: Sorry, boss, it’s hard to keep track.
