Do's and Do Not's

I can't wait to share this.  Three things you should never have in your house:  Cheap toilet paper, fat-free dressing, and a knife so dull you can't cut butter.  In contrast, three things that're ok to have are cheap batteries, cheap ketchup, and cheap knives that you're not afraid to use and abuse.  Just don't cut yourself.  That's it, thank you.
