Trying out new toothpaste

When I came home from the event I volunteered at on Halloween, my hands were covered with paint.  I had a concert the next day (a really formal one), so I spent a lot of time washing my hands that night, which is why it's kind of funny that I didn't notice that my toothpaste had thrown up all over the sink.

I was trying out a new kind of the toothpaste I use.  The new kind comes in a cool, futuristic dispenser (I had a coupon).  It's worked fine for the last month, but now whenever I use it, I come back later and find that it has vomited up a truly appalling amount of paste onto the counter.  (Where is all this paste hiding?  It's not that big of a tube!)  I don't know why.  The dispenser doesn't seem like it's jammed on or anything.  It just sort of oozes up a pile of blue when I use it.  Back to the drawing board, folks.



Have you ever tried out a new product and gotten something other than what you thought you'd get?  Or found it doing something not advertised?
