U.S. President Barack Obama made history last night when he appeared on a comedy show, which some say further demeans the dignity of the highest office in the land.

Obama was a guest on the popular ‘Daily Show With Jon Stewart,’ last night.

Stewart, who is a Democrat, has been critical of Obama’s politics in the past. But the political comedian/mock news anchorman took it easy on the commander-in-chief.

Stewart called Obama’s attempts to reform healthcare “timid” and he jokingly referred to Obama’s campaign slogan “YES WE CAN” as “Yes we can, given certain conditions, blah blah blah … blah blah.”

When Obama said, “Jon, I don’t want to lump you in with a lot of other pundits,” Stewart retorted with an equally cynical jab: “And I don’t mean to lump you in with other presidents.”

At one point, Stewart even called the president “dude” after Obama inadvertently echoed a famous George W. Bush gaffe by saying that his economic adviser, Lawrence H. Summers, had done “a heck of a job.”

Mr. Obama winced as the audience laughed at his wording and Mr. Stewart said, “You don’t want to use that phrase, dude.” [link]

Obama’s next TV appearance will be on the History Channel’s nerd fest ‘MythBusters’ next month.
