Great ideas can form at any moment. For instance, in the middle of an interview with Thomas Lennon on 'The Late Late Show' (Weeknights, 12:37AM ET on CBS), Craig Ferguson stumbled on what could well become the next exercise craze.

It was when pogoing came up, Ferguson asked Lennon if this was a new thing. "Are people doing that now? Is that the new pilates?"

"That could catch on," Lennon mused. And then they were imagining promoting it via interviews, talking about how great it made them feel.

"You get one Kardashian on a pogo stick!" Lennon said, but this is when the conversation derailed. Because Lennon can't pronounced the name correctly. He says it "Kar-day-shian."

"You're saying it to appear smarter than you are," Ferguson accused Lennon, equating it to news reporters who roll the "R" in Latin American country names. Lennon apologized for anything he might have done to embarrass the family, leaving Ferguson open for a great dig at them.

"No, they've done everything to embarrass the Kardashian family," he said.
