A replacement battery for your fire alarm so it will stop beeping and freaking your dog out. And I'll second siex133, don't panic and grab your towel. And Lee, guys have been doing that for years in the shower even if they have toilet paper.

Flashlight, pocketknife, pen. Personal first-aid kit, multi-tool.

Well, isn't that just about everything?

I'll add toilet paper and important documents (ie social security card, passport, etc) to the list. No connection between the two though.
