1. There is a radio station that is still playing this song.
2. The person still has a tape deck in their car, and they are playing a tape from 1990.
3. They have purchased The Humpty Dance as either a CD or a download.
None of these options makes any sense to me. For those of you who don't remember this iconic song and dance, here are some lyrics:
My name is Humpty, pronounced with a Umpty.
Yo ladies, oh how I like to hump thee.
And all the rappers in the top ten--please allow me to bump thee.
And, of course, there is video of the Digital Underground performing on the Arsenio Hall show. Supposedly Tupac is one of the dancers, but for his sake, I didn't look too closely.
