The dude gets extremely drunk and wakes up in a cemetery at night.

First he looks around quite puzzled and trying to remember how he got here in first place. Ah well, okay, who cares? - it's pretty late so he decides to find his way home first and to think of it later. He wonders around a little and sees an exit - and a gravedigger quietly working nearby. The dude still being quite intoxicated decides to fuck with him a little before leaving. He quietly sneaks behind the gravedigger and trying to sound as creepy as possible whispers in his ear: 'Wooooooo!' The gravedigger doesn't even seem to acknowledge him and keeps digging. So the dude goes a little louder: 'Wooooooooo!!!'. Nothing. The dude thinks the digger might be deaf or something screams on top of his lungs: 'WOOOOOOOO!!!' The gravedigger gives absolutely zero fucks, so the dude gives up and starts to walk away towards the exit - and then suddenly gets a hard blow to the head with a shovel. And the gravedigger says: 'Yer know them rules mate - you may be foolin around as much as you like, but you're not leaving the area!'
