More for the "you can't make this stuff up" department.
According to the instructions, after you've circumgyrated the telescopic stick, you:
"Pull up and down the stick, denched the stick by your hand, put it up and down slowly, prevent the fast up and down ..."
I think this will fit right in to my next story, whatever it ends up being. There's always a place for "slow up and down."
And all this to put up a projection screen.
