Crime, coffins, and assorted craziness

I can't tell which is the funniest part:

1. that the thieves beat the funeral parlor employee until he fainted;
2. that the employee was nailed in a wooden a coffin for the remainder of the burglary; or
3. that the employee was freed from the coffin by the hearse driver?
   

Seems like this was taken straight from the script of a bad heist movie.
