It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, Percy walks up to the doors and tries to open them, but can't. Vax prepares to unlock it, but there isn't a lock; the doors are barred from the inside.
DM: There appears to be something on the the altar in the distance, small and scattered about it, but from this distance, it's hard to make out the details. But you hear Vax muffled through the door.
Player: All right, how big is this thing that's keeping the door shut?
DM: It's about eight feet wide and about a foot-- eight feet long, about a foot wide and about six inches thick. A big old piece of wooden board.
Player: A couple hundred pounds?
DM: I would say it probably weighs about 40 or 50 pounds.
Player: 40 or 50 pounds?!
DM: It's wood. It's porous.
Player: And how high off the ground? Could I touch it?
DM: You could touch it. It gets to about your head, a little higher.
Player: All right. I'm going to try and lift it off.
DM: Go ahead a make a strength check. Athletics! Make this athletics.
Player: Athletics? Hmm. Not good. 12!
DM: (grunting) From this position, it's not even budging.
