A man gets a job on a train...

A man gets a job on a train. He starts off as anyone does, as a lowly janitor. He sweeps the floors, cleans the seats, and scrubs the windows. He doesn't get paid much, but he's a hard-working man, and does his job well. He's such a hard worker that eventually he gets promoted to ticket collector. He collects tickets very quickly and efficiently, and is happy with his job. Eventually he gets promoted from that job, and makes his way up the ladder and up the train until eventually he makes his way to conductor. The train company has high hopes for him, given his previous reputation. But although he was a very hard and skillful worker in every other job he does on the train, for some reason he can't do this job well. He keeps making mistakes and eventually falls out of favor with his coworkers. He gets demoted to possibly put him in a job he better belongs. But still, even in the lower jobs, he can't seem to his job right. He gets demoted and demoted for poor performance, and eventually fired from the train company. He runs out of money, loses his house, and is living on the street. He gets hungry, and desperate. Out of necessity he decides to rob a convenience store, just to have a bite to eat. He holds up the cashier at gunpoint, but while stuffing his pockets with food and money, a cop walks in. The man gets scared, and shoots the cop dead. He gets arrested and brought to court, where the judge sentences him to death by electric chair. So, defeated and shamed, he is brought to the electric chair. They strap him in, charge up the machine, and flip the switch! But nothing happens. They turn it off and then on again, still nothing. They turn to the man, confused, and he chuckles to himself.
"I guess I just wasn't a good conductor!"
