Tomb Raider 2: I always lock the butler up in the freezer in Lara's Home. I do this now because it's fun, but I did it back then because he scared me.
Oh my God yes. Then he'd try and walk through the door and the horrendous clipping would make it look like he was half in and half out. All the while he's making muffled groans. I used to actively avoid the tutorial level on both TR2 and TR3.
