Quinton "Rampage" Jackson could only smile as a translator struggled to convert something he'd said into Japanese. He tried to explain it twice before giving up, shaking his head and laughing.

"Man, I got to get fluent in Japanese so I can translate my jokes," he said.

That was about the only problem Jackson ran into as he held court at the Ritz Carlton Tokyo on Monday to help announce his return to Japan at next year's UFC 144 in Saitama, where he'll face rising star Ryan Bader.
