Comedian Frank Caliendo gained prominence by imitating the voices of Presidents Bill Clinton and George W. Bush, among other luminaries. This weekend on 'Huckebee' (Saturday 8 PM ET on Fox News), he broke out his new Obama impression, though admitted it's still a work in progress.

"(Obama) begins sentences with the words 'look' or 'here's the deal,' Caliendo explained to Huckabee's audience, while imitating the President. "Now if he says both of them he thinks it's pretty important, and its probably going to cost you a couple bucks."

It's the cadence, like he talks slow at the beginning," Caliendo continued. "And-speeds-up-at-the-end."

Given the lack of good Obama impersonators out there, Caliendo's early efforts are already pretty solid. Still, it's unlikely Caliendo will become the go-to imitator of the president, because, as he pointed out "it (looks) like Cartman from South Park trying to do him."
