I love to discover random inventions that totally make life easier (example: using a micro plane as a cheese grater). Newest find: the tooth paste tube squeezer, which Jon and I marveled over at a friend's sink. I tracked it down (that is the technical name) at a local Bed Bath & Beyond store for around three bucks for a pack of two, but you can find them online at Amazon and Organize.com.
Seriously, genius. Get one and thank me.
