We were listening to the radio the other day, Peter Gabriel's Sledgehammer was on. Lucas said, "I like this song, it's about superheroes."
After the song was over, I found what I thought was another superhero song on my iPhone, I Am Superman, from REM. But according to Lucas, this is NOT a superhero song, it's a "girl" song.
So then I kind of gave up and we were listening to some international fare. He said, "I don't like this Scooby-Doo music. Turn it off."
