He did it on purpose!
But he has a hard head! ^^
I did that to a front door once :-[
Not as spectatular :(
Some automatic doors have rotten sensors. I've lost count of the ones I've walked up to and they've failed to open. What to do then. Back up and try again? I stand there and wave frantically at the sensor to tell it I'm there, while feeling a tad insignificant. :-<
I hate technology. What was wrong with the bloody door knob? >:(
