wtf... but yea man i let my pizza sit out since the box can't fit in my fridge then i just throw it on the frying pan and get down... you won't die op...
I routinely eat many things left out over night or all day on top of the stove. Most stuff has to be sitting out for probably around 24 hours before you need to start worrying. Some things may go stale or get hard faster than others though. And I'm talking hamburger meat, chicken, pizza, pasta, pretty much anything, I've probably eaten it right off the stove the next day. It's fine.
Fixed, now you got your 2nd bar (my +rep is worth a ton). I love room temp pizza, just as good as hot in my book.
I disagree strongly... it might have some extra shit in it if you go to a chain, but local pizza places definitely use real cheese.
