No Rock And Roll Fun

I'M NOT SURE THIS HELPS: Spizzazzz offers an explanation for why nelly wears a band-aid on his face - apparently its "for his little brother who is in prison." I'm not sure the logic behind this unravels that easily in my mind - is he suggesting that those incarcerated in the US Prison service aren't allowed the luxury of sticking plasters, and so he is wearing an Elastoplast so that his brother might feel some sort of fraternal empathy working on some sort of postule? Is he suggesting that having a slightly itcy oblong of gum on his face means that he's suffering side by side with his brother? Is this like tying a knot in a hanky as an aide-memoire? "Yo, Nelly, where's your little bro?" "Hmm... can't remember... has he gone to the shops? Has he popped off for a fishing holiday? [Rubs face in thought] Oh, now I remember, he's in prison..."
