Blah, did it once, and the DM forced a bad taste in my mouth as a result.
Our party's paladin fell in battle against a "Not Drow! Just a blue-skinned elf the GM home brewed" Ranger enemy NPC with favored enemy (elves). Oh, and the baddy was not "Evil" (in spite of having hos own race as a favored enemy). Anyhow, we managed to defeat the enemy ranger, and we were in sight of this massive black-dome (Not evil!) which was the city of shadows (NOT EVIL!) where the (not drow!) dark elves lived.
I said that this couldn't possibly be a safe place to hold a burial, and opted to put the paladin's corpse in the bag of holding so we could give him a proper send-off when we were safer.
The GM was appaled by my lack of reverence for the dead. We were (*cough*railroaded*cough*) captured by the (not evil) dark elves and placed in a prison where the bars were too narrow to fit a finger through. Then *cough*freighttrain*cough* put into an arena pit where a GMPC saved us *cough*sightseeing*cough*. He also got us back all of our equipment (minus the paladin's corpse)
After the whole affair concluded, the GM handed out experience and I leveled, but the GM said i could no longer level as a monk because I had behaved too chaotically, citing the paladin-inna-bag specifically.
