In college, anytime anyone said something funny, some theater major had to ruin it by saying, "that should be a sketch! for our sketch show! we should recreate THAT EXACT MOMENT THAT JUST HAPPENED FOR THE FURTHER GLORY OF MY SKETCH COMEDY GROUP!"
now, in LA, the line is, "That should be a short film! That's a short right there!"
and it's true, almost anything that has ever happened could be the subject for some sort of short film. but that doesn't mean you have to say it. it doesn't give you "dibs." just make a mental note and try to stay with the conversation that's currently happening, OK?
