That's a Liquid?

Monday, the moving guys showed up to pack and load up our stuff. They did do a pertty good job. However, I was a bit confused by some of the things that they put in the liquids box. (They couldn't take any open liquid containers.) Here is a list of some things that ended up in that box:

A yellow ceramic duck.
Razor cartridges.
A pregnancy test. (It's positive by the way)
An electric razor.
Feminine hygenie products.
Q-tips.
Cotton balls. (Just kidding about the pregnancy test being positive.)

What, are the moving guys from Oregon or something? I guess when our kids are going to school and learning about solid, liquids, and gases, we can let them know that the yellow duck is a liquid.
