Detailed walkthrough
The goal is pretty simple. Just go buy a shovel from Chet and start digging up some graves at the Goodsprings Cemetery for loot inside. Unlike in Fallout 2, you won't be called a "Grave Digger" and your reputation is not affected either.

There is an abundance of loot to find in the graveyard, namely a snowglobe which can be handed in to Mr. House for 2000 caps as well as a couple of cigarette butts laying around your grave which will serve as evidence in incriminating Benny. Beware of the Bloatflies, though, as they can be a hindrance to an opportunistic gravedigger.
