Block the Door

Norm pushed his bed flesh against the door. It created a horrible noise and I hoped to God that no one heard it. "Could you be more quiet?" I ask, annoyed. "Unfortunately. I can not." "Enough bickering. Did you successfully block the door?" Olivia asks. "I did, but we have a new problem." "I sigh."What now?" "The only way out is if you guys smash the wall." "Can't you climb through to this side?" Olivia wonders. "Nope. I need both my arms for climbing. I only got one right now." I turn to Olivia. "Any ideas what we can smash the wall with?"
