Shaquille O'Neal may be 45-years-old and out of playing shape, but the big man was back on a Reebok-sponsored camp, showing younger dudes, he's still The Big Diesel for a reason.

The former terror of the NBA put on a display of strength in a game of pick-up basketball, giving the old stiff arm and dunking it like it was 1993 to the amusement of many.

Boom-Shaq-a-laka!

O'Neal hasn't played in the NBA for six years now, but he's still every bit of the 7-foot-1 monster he was back in his day, and probably more than the 325-pound playing weight he was at when he last played.

Something about a rim and backboard earthquakingly shaking after a dunk brings a true nostalgic memory of his playing days, where the victims weren't just random strangers at a gym, but just about any defender foolish enough to challenge him in the paint.
