Albert Pujols

David Letterman literally stepped up to the plate with 'Late Show' (weeknights, 11:35PM ET on CBS) guests Denis Leary and baseball slugger Albert Pujols.

"You and I and Albert Pujols will be out on 53rd Street and, if you don't mind pitching, we're gonna take a little batting practice," Letterman told Leary.

The actor said that pitching would be "a thrill. But I saw the little protective thing you have for the pitcher -- doesn't look very protective."

But he obliged for Team Late Show. Letterman went to bat first and didn't do too badly. But of course, the nine-time All-Star and three-time MVP was better. "I thought you were pitching," Pujols said to Letterman. The host threw him a couple from the side.

I can't help but think of the old "Bo Knows" commercials, where professional baseball and football player Bo Jackson showed us that he could do literally anything. Now, it's the big man's turn. Shaquille O'Neal stars in Shaq Vs., where the basketball star shows his own diversity by taking on the likes of Michael Phelps and Albert Pujols.

The idea is that Shaq will take on the guest athlete's sport, meaning he'll swim laps with Phelps and go to bat against Pujols. The ABC series premieres Tuesday, August 18 at 9 PM, but there's no word as to how many episodes they're signed up for. If it's a huge hit, though, you have to think they're going to need to find more athletes and more challenges for Shaq.

Can he Trade powerslams with Randy Orton? Pump more steroids than Manny Ramirez? Make a better blacklight sex tape than Paris Hilton? Get more tabloid headlines than the Gosselins? The real challenge would be if Shaq starts taking on actors in their chosen field.
