1/4 Stewart's Fountain Classics

At our  Wal-Mart date we picked up some very unnecessary items -
Like Stewart's  Key Lime Fountain Classics
I have a thing for Key Lime.

Smooth lime taste - just like the bottle says!
Yet it leaves that little delightful
key lime tingle in your cheek/jawbone area!

In this case, I am a fan of the unnecessary.
What do you have that is unnecessary, but that you enjoy immensely?
