In horror movies when someone says "I'll be right back"... they WON'T!!!!also the houses seem to be devoid of light switches / torches/ candles.. so you go chasing the monster / psychotic killer in the dark!!!
in old western bar fights... they can roll over tables, be thrown through window or across the bar... and the goody's hat will always stay on......
in musicals.... someone will nearly always have a barn / hall/ shed... where the show (which would otherwise have to be cancelled) can be put on....
