Alright so one time me and my friend had just smoked outside, so we cam inside and we had to lock the door. This door is kinda old and you need to push on it so you can turn the deadbolt. Well I was pushing as hard as I could, and couldn't get it turned. I called my friend over and we both pushed as hard as possible, and we still couldn't turn the deadbolt. So we tried opening the door to see if it was broken, and "OH SHIT! WE PUSHED IT TOO HARD!". We pulled on it as hard as we possibly could, and then I went back to push from the other side. Finally I notice the door is moving, but is stuck somewhere. That somewhere happens to be the deadbolt, I told my friend to turn it and it unlocked and opened easily. Laughed for about 30minutes after that, heh.
