I guess I'll toss one in here... if you like sitting in those over-wing exit aisles...
Almost all safety cards show people removing the "plug" style over-wing exits and pulling them inside the cabin and setting them in a seat.
First off, they're heavy, be aware they're not lightweight.
Here's the tip: If it's a REAL emergency and you have to go out the over-wing exit, the only thing it's going to do if it's inside leaning on a seat is get knocked over, fall on someone's foot and break it, and/or become an obstacle to people trying to get out that exit.
Turn it sideways (it's bigger than the hole it's in, of course, since it's a "plug") on-edge, and give a big heave and throw the bastard out through the now open hole. It'll dent the wing. Not your problem.
The caveat here of course is, if you do this sitting on the ramp and the flight crew didn't even want folks going out the over-wing exits, you're probably going to be talking to an airline attorney who'll want to know how you're paying for the dented wing.
But in that one-in-a-bejillion that you find yourself in a broken airframe with people trying to get OUT and you're the person standing at that silly little thing... toss it the hell outside.
