Drunk falls into an open grave

[rebbonk]

A drunken fellow leaves a bar and decides to take a short-cut through a graveyard. It's very dark and raining heavily. He fails to see an open grave and falls into it. He tries to climb out, but the sides are just too slippery and it's too deep. After a while, he realizes he can't get out by himself and stops trying, deciding to sit and wait and hope someone walks by.

A short while later, another drunk leaves the bar and decides to take the same short-cut through the same cemetery. He also falls into the same grave, and tried to climb out, but the sides are too slippery. The first drunk is still sitting there and watches as the other drunk tries but fails to get out.

Finally, the first drunk stands up, taps the second one on the shoulder and tells him "You'll never get out."

Spoiler:

He did.
