Me (singing): All around the mulberry bush, the monkey chased the weasel, the monkey thought it was all in fun, Pop! goes the weasel!
Her: What does that even mean? What is that song supposed to be about?
Me: Unexploded ordinance.
Me: Yeah. It's from a German post-war children's song, "Boomf Geht Der Weasel."
Her: Because it does seem like something the Germans would sing about.
