Halfway through the flight, this one guy, several rows in front of me, decided that he needs to visit the toilet.
Unfortunately for him, he is the window-seat guy with two moron neighbours who didn't think to stand up and get out to the aisle to make way.
So the poor chap has to struggle clambering over two sets of protruding leg obstacles.
Forgetting that he has a screen overhead, he rammed his head into it so hard that it triggered the screen to retract back to its nesting.
Fella panicked as he was afraid of incurring the wrath of the other passengers who were watching the movie mid-way. He stopped in his tracks as he tried to figured out how to get the screen back down again (all this while his butt probably inches away from the middle-seat lady's face). He felt around hoping to have a release button. None found. How about using his fingernails to pry it open? Nope. That didn't work either.
Then all of a sudden, the screen popped open again smacking him in the head, albeit relatively gently as the screen swing motion was rather slow.
Still, it was funny as hell.
AND this is why I ALWAYS take the aisle seat.
AND yes. I do stand up, get out onto the aisle for fellow row passengers to get in and/or out.
