16 year-old (student) GM blew me away tonight, delivering his half of this colloquy with a straight face and without missing a beat:
PLAYER: I examine the artwork and motifs in the wooden panels, trying to dredge up some knowledge of the history of this place.
GM: Sure. Give me a History check.
P: 4.
G: "Boy, this sure is an old house," you think to yourself.
P: I stand back in soak in the oldness of the house, trying to perceive what I can about its here-and-now.
G: Sure. Give me a Perception check.
