Above is a video of Shaq acting a fool and acting like he's auditioning to be on the NBA2k15 soundtrack which is "curated" by Pharrell Williams. The rap is intentionally bad but most people will probably think that's about as good as Shaq can get on a mic.  

I'm in the minority that doesn't think Shaq's that bad - especially compared to half of the rappers making music nowadays.  I helped contribute to his first two albums going platinum and gold and even bought the horrible Respect album (which featured a secret guest appearance from Kobe Bryant) and Steel soundtrack which probably didn't sell more than a few thousand units. I was even waiting for his never released Superfriends album.
