Slow Jam doesn't even have a real fucking title, honestly, do NOT attempt to seek wisdom and meaning in there.
I always picture Barney laughing his knackers off when he turns out stuff like Slow Jam, or that "in the corner over there" line that upsets a lot of people and amuses me greatly.
Even in songs where he's being deadly serious, I find, his lyrics are often a few BREATHTAKING couplets, little 2 liners that The Bard himself would be proud of, tied together with a lot of lines that are less elegant and profound, and often just daft. There's no way it's cos he can't write great lyics for a whole song (cos there's plenty that are amazing beginning to end), he just has a really fucking odd sense of humour (and doesn;t he despise writing anyway?).
That' my £0.02 on the subject anyway.
EDIT: I bet you next week's pay that he does it partly to upset the likes of you PSQ
