This'll be a quick one for a change.  Y'know what really grinds my gears?  When characters on tv, especially cartoons, are cutting onions.  Yes, it makes your eyes water, ok, but cutting onions doesn't make you SAD.  It doesn't make blubber and sob and go "WHAAAAAA HAAAA HAAAA HAAAAAAA!"  It doesn't make you bawl like Rainbow Dash when Tank died.

... or... hibernated... or whatever.
