One night after brushing my teeth I rinsed my brush and set it down on the mantle, and then I forgot about it.

Next days I came downstairs and any and all leftover stuff in the toothbrush had leaked onto the mantle, and when I pulled it away, this cheery little stain was where the bristles had been.

Couldn't believe my eyes when I saw it, but there it was and after giving up on how it could have been made like that I pulled out my DSi and took a pic of it ^^

Cheeriest little stain I ever did see =3
