Why does Edmund Mcgenics use the mewgenics budget to make professional grade songs about his trauma? Is he sexually frustrated?

Ridiculon: OK Edmund, what should the ice age song be about? Cavemen or something?

Edmund: So what if the cat's mom was, like, really sorry for leaving them and begging me for forgiveness. Err, I mean the cat.

Ridiculon: But what about the cavemen?

Edmund: Yeah I dont care do another version where all the words are Unga bunga or whatever. But make the song about my mom first.
