I'm just focused on this one, because it's so out there. I mean, I know you weren't serious, but lots of songs were popular in our childhoods, but you don't hear people doing "Rock Me Amadeus" or "I'm Too Sexy." Picking Biz Markie is still mysterious for ONE group, let alone two. It's almost as if the "Total Eclipse of the Heart" thing had caught on, AND someone else was doing the same thing.
It's gotta be that commercial.
Now I'm all obsessed with finding a new bizarre chant that catches on. I guess it has to be organic.
Although I will say I saw you mention Macho Man in another thread. I think it can happen.
