From the too good to be true range...
For the matinee performance of one my school's plays, the special education students were brought into the auditorium in their wheelchairs and parked in the front row. To prevent the students in the motorized chairs from going anywhere, the teacher turned off the power on their chairs.
Being the light-board operator I had seen the production several times and was paying more attention to the audience than the show. About halfway through the performance, one of the handicapped children caught my attention; he had pushed himself out of his chair. I watched him for about twenty minutes as he pushed himself further and further to the right, until he finally reached his goal.
A boy in a motorized wheelchair, who had fallen asleep on his joystick.
Motorized wheelchairs are capable of decent speeds, it seems. So when (after twenty minutes of sterling work, mind you) the crawling young man flipped the power switch on his neighbour's chair, the hapless sleeper was rocketed forward full throttle, slamming the chair into the low stage.
The now very much awake student flew - in that slow motion way that disabled people flying out of their wheelchairs have - onto the stage. The actors stopped, the audience was aghast, and the only sound louder than the wailing cries of the student on the stage, was the hysterical laughter of the young man on the floor where once a wheelchair was parked.
