As often as they brought up "Pig and Elephant DNA just won't splice", I kept thinking it was a parody of some song or singer. I tried googling it back then, but never found anything.
Keeps shifting lately. It was 11pm to 4am for a long time, but I've been waking up almost hourly and going back to sleep. Recently, I've been lucky to make it to 10pm on workdays, and waking up between 3am & 4am.
