Mash-Up? More Like Mash-DOWN

Our son decided we would play his version of Mash-Up this weekend. He had no hard-and-fast rules, so the mash-ups could be anything from the name of a car suffix with the name of a movie director to a type of food suffixed with the name of a singer. It was a little too broad for me to have a chance guessing the two parts. We ended up tweaking it to (usually) two actors or singers names.
