I woke up to find that I had scrawled the last line of this sleepily on a sheet of paper on my desk. I shouldn't have listened to the 70's hit marathon on the way home from work the night before.
The comic provides alternate lyrics to the chorus of the 1975 song "50 Ways to Leave Your Lover" (Video) by American artist Paul Simon. Both the original and alternate lyrics provide a textual hook because the name at the end of the line is rhymed with the word before it (back/Jack, plan/Stan, go/Joe).
Randall, we learn from the title text, heard Simon's song during a '70s hit marathon, went to sleep, and while being tired replaced "lover" by "hover" while writing the last line of the song's chorus. Thus changing this line from to leave your lover into to learn to hover. Clearly, this amused him so much that he decided to create a comic where people learn how to hover, rather than leave their lover.
