Adventure Time is surreal.
But of course Pendleton has to include innuendo, one of them being peppermint butler revealing that he is a homosexual by telling a boy that he wants his babies.
At the end of the same episode, he smacks PB for setting the boy free with an android clone of herself and exclaiming that she "should have left him to me"
Ok, innuendo in kids shows, that expectant of the 21st century.
