Just in case you didn't know: tiny jets.

You know those tiny jets that have two seats on one side of the aisle and one seat on the other and the seats are really, really close together? Just in case you didn't already know, the RECLINE feature on those seats is like the ashtray in your car. It is not meant to be actually used, it's just there because it has to be. If you doubt me, the next time you get on one of those tiny jets ask the person sitting behind you.
