Back when he was a basketball player, Charles Barkley was known as "The Round Mound of Rebound." This nickname alludes to the fact that he was great at grabbing rebounds -- and to the fact that he was a little, well, pudgy. And that was when he was a professional athlete. Once Barkley retired from the game, he really started to pack on the pounds.

On the new 'Lopez Tonight' (weeknights, 12AM ET on TBS), Charles discussed gaining weight, losing it, and how going through airport security is a real problem when you're fat. After leaving basketball, Barkley put on 100 pounds, leading to difficulties with a TSA agent. "You know how they ... reach up under there?" he said, gesturing to his chest. "The [agent's] hand disappeared."

Sadly, Barkley was so overweight that the agent's hand got lost in his "round mounds." "I had man-boobs," Barkley admitted. George Lopez did his best to console Charles, bringing out an anatomical doll -- though for some inexplicable reason, it was a "Harry Potter" doll. "Show me on this doll where the TSA agent touched you," the host said.

Charles complied, demonstrating the various places where he was "patted down." Via the Harry Potter doll, he was able to show that the agent grabbed a "mound" of an entirely different kind. We won't get into details, but instead will just say this: Barkley definitely didn't follow the example of the "Don't Touch My Junk" guy.
