I always eat stuff out of date, unless it's a mess and clearly badly off.
I can't stand germophobes or people who shit themselves about every little thing that goes in to their body. It just annoys the shit out of me, man up - you're not made of glass and you will not die from a bit of bacteria.
I did something gross once. We lived in a proper messy student house with a mouse problem, not a huge one, just the odd one here or there.
Once, I ate a load of toast and the following morning, my mate pointed out there was a crushed, mangled mouse in the toaster - it must've been scavenging, and I crushed/burned it to death.
My best mate (pure germophobe, not that dead mice and shit isn't worth worrying about!) was scolding me, and we noticed that there were mouse droppings around the toaster as well. I stuck a few in my sandwich, got it down me.
Stupid and disgusting thing to do, and I'm not really sure why I did it, other than to make him sick and prove that it wouldn't do fuck all to me....it didn't but fuck, it could have!
