Corrected entry: When Harry and Marv get hit by the toolchest, Harry asks, "What's that sound?" Marv answers, "That was the sound of a tool chest falling down the stairs." They had not been on the staircase it came from, and had not seen the tool chest or the stairs - both were blocked by the door.

Correction: Considering the amount of noise the toolchest made, it's not a stretch to think that they were able to deduce what it was.
