A friend of ours (wife and i) was woken by his wife late one night, "there's someone in here" she said nudging him out of bed. My buddy goes an easy 350# and is maybe 5'6'' tall. He grabbed his 30'' barrel single shot 12ga and proceeds to have a peak. As he went from the hall towards the kitchen he must have, in his groggy condition, let the gun go horizontal. The doorway was to narrow it caught on both sides and made a horseshoe out of it. Broke the receiver. Turned out the cat knocked something over.
