WATCH: Keith Olbermann and Michael Moore follow Bill Maher's comedy double-header

ESPN host Keith Olbermann and filmmaker Michael Moore donned sportscasting blazers on Friday as they "covered" Real Time host Bill Maher's six-block jaunt from his season premiere to a live stand-up special.

"We're seeing something unprecedented in comedy tonight, Michael," Olbermann said. "A man trying to be funny for an hour in one theater, and then stopping the funny, then getting into a car with a motorcade going through Washington [D.C.] and then trying to be funny later on. This has not been attempted, we believe, since Archduke Ferdinand in Sarajevo in 1914."

"And then repeated again for eight years during the George W. Bush administration," Moore added, drawing a cheer from the audience at the Warner Theatre, site of the second half of Maher's live experiment.

The transition began immediately following the end of Real Time, when Maher dashed off-stage and changed from his suit into a more casual outfit, but Moore worried he rushed the change.

"It does not look like Bill is wearing his protective cup," Moore fretted.

"I hope nobody was looking for that," Olbermann responded.

Maher then hopped into a limousine, which took him from Sidney Harman Hall to the theater with the benefit of a police escort.

"Clearly, the $1 million he gave to Barack Obama has paid off here tonight," Moore gushed. "Nobody can travel through Washington D.C. this fast."

"This is, once again, your tax dollars in action," Olbermann added.
