Don't sell your self short, Bob. You've made a far deeper impact in the world of rap than just that one 2003 song. I was able to find three other instances where you've been name dropped. At this point, you're a true Triple-OG.
“The Last Huzzah” – Danny Brown, Das Racist, Despot, El-P
“Don't love the game, shot clocking above the game/Ballers and shotcallers be calling me Bob Costas”
“We Major” – Domo Genesis
“Rasta; but no dread-head, I'm too proper/I'm breaking down the game for you niggas like Bob Costas”
“I Get Down” – Shad
“While imposters talk and jock like Bob Costas/This colossus is so pompous its preposterous”
And, of course, the original.
