I think the Bootsy reference is the hip skull sunglasses. Also, I think that Ray is probably the first outside-thong-wearing goth on the planet.
Ray, why must you ruin everything LN enjoys? WHY?
Look, no offense to goths or thugs, but if I were a parent, I wouldn't want my kid being either of those things. The humor, for me, comes when Ray acts creatively to try and make his kid act how he believes is "normal". I bet if LN became a skater punk like Ray was back in the day (hell, he could borrow Beef's DK shirt) that Ray would be all about it. He just doesn't want the kid being like those kids that he hated back in high school.
