WATCH: Anderson Cooper Disses VP Joe Biden for Skipping Paris Rally

Laughs and applause aren't something CNN's Anderson Cooper typically hears when he talks about world events.

But he got just that in an appearance on Late Show With David Letterman this week. As the outspoken gay anchor recounted his experience covering last weekend's massive peace rally in Paris, Cooper took a shot at Vice President Joe Biden, who was notably absent among the world leaders in attendance.

"[Biden] spends weekends watching, like, Gilmore Girls on his DVR," Cooper quipped. "I mean, what else does a vice president do?"

"Does he?" asked Letterman with a smile. Cooper admitted, "I don't know," and added he meant no disrespect. "But that's basically what vice presidents exist for."

Although Biden bore the brunt of his sarcasm, Cooper also gushed facetiously about President Obama, who was also conspicuously absent from the march.

"To see President Obama there was just extraordinary," Cooper told Letterman, wryly.
