23 Toothpastes, 1 Cup
As a pro-toothpaste American (it's so much better than tooth powder, let me tell you), I was thrilled to see this post on Boingboing about a guy who used all of his toothpaste samples and leftovers to create a giant, toothpaste suicide! Basically, he squeezed out all of his sample packs and nearly empty tubes into a bowl, and then mixed it up to create what should have been the most disgusting paste ever. Instead, it apparently ended up being pretty minty, with some spicy overtones. In any case, I just love the gooey, colorful photos.
