Jay Leno Hears Crickets After Casey Anthony Jokes (VIDEO)

You know your joke is bad when your audience, who spent hours waiting outside in line to get into your show and is prompted to laugh at your every word, goes silent. We're looking at you, Jay Leno.

Leno was one of only a few news-covering comedians on the air last night, as "The Daily Show with John Stewart" and "The Colbert Report" were on vacation. So it was up to Jay to joke about Casey Anthony, who was determined innocent last night of everything except for providing false information to police officers, which is a misdemeanor.

"It was so hot today, people were as delirious and incoherent as a Florida jury," joked Leno, which was met with applause. But when Leno continued on and said "This means President Obama’s economic team is only the second most clueless group of people in America."

That second joke was met with near silence and a few groans, and Jay quickly turned to the crew, asking if his mic was off. That lead Leno to actually tell the joke again, which got the audience to laugh.

Was it actually a technical problem, or were people just annoyed at the joke? They applauded at the first Anthony joke, so was it just that the Obama reference fell flat?

Check out the video below and let us know what you think. The jokes start just after the 1:00 mark.
