David Letterman Defends Chevy Chase In Tense Joel McHale Interview (VIDEO)

David Letterman seemed determined to use Joel McHale's appearance on "Late Show" (Weeknights, 11:35 p.m. ET on CBS) to try and defend the good name of his friend Chevy Chase. McHale has spoken on occasion about the controversy that surrounded Chase and "Community" creator Dan Harmon, but he himself never seemed to have any issues with his co-star.

Nevertheless, Letterman and Paul Shaffer were adamant in their defense of Chase's reputation, calling into question the veracity of some of McHale's stories about Chase trying to goad him into fist-fights on set.

The result was an interview with a very weird vibe. At times, it looked like McHale was laughing the whole thing off, but at other times he looked genuinely uncomfortable. And then, to wrap up the bizarre segment, Letterman cut to a picture of Chase just before the commercial break.

"Community" returns in the fall. "Late Show with David Letterman" airs weeknights at 11:35 p.m. ET on CBS.
