Since winning his fourth NBA title in 2006, Shaq's dabbled in everything from law enforcement to professional wrestling and received a doctoral degree in education from Barry University. O'Neal's industriousness doesn't surprise us at all. Dude tweets every 30 seconds and can't go six months without launching an ill-fated reality show. He's like Khloe Kardashian, but with a weaker turnaround jumper.

Today, Shaq's an analyst on TNT's Emmy Award-winning "Inside the NBA" broadcast team, he's reportedly squashed his beef with Kobe Bryant, and he's spearheading a campaign to help people with diabetes. Alas, a post-retirement career the NBA can be proud of.
