You have to pick:

If it rained pasta you could just open your mouth and eat it, but pizza toppings would be messy

that would probably hurt, and eventually your roof would cave in under the weight

heaven

in it's purest form

Unless they are hot.

Also, what about what doesn't get eaten. That is NOT going to smell good in three days.

The smell you'd get use to, rotten cheese and meats, you'd get use to it until it didn't smell.

Also since it rained only pizza toppings either our blood is marinara sauce or we'd die from dehydration/diabetes/heart attack real fast.
