Just watching some video clips reminded me of 2 episodes.
1. I was entering a cake shop, clear glass door and I walked straight into it. Laid out in the street, Knocked myself out for a few moments
2. Was more recent. My garage doir is electric. I pressed the remote then picked my shopping out of the car and turned to carry it through the garage..... only the door had only opened part way. Bang!! Head first into the edge and I was laid out on the drive..... don't know howl long I was out for.
