We get it. Summer's winding down, work is back in full swing after a long holiday weekend, and you need a laugh. We've collected the five funniest TV moments from the past week for your viewing pleasure here. Prepare yourselves for two hysterical cameos, heavy flirting between a late-night host and an actress, an emotional freak-out and more. We dare you not to chuckle.

There seems to be an epidemic of blabbermouthing going around these days. First, Vice President Joe Biden's wife Jill lets it slip on Oprah that Joe had his choice of VP or Secretary of State (snap Hillary!), then Steve Martin reveals that he and Tina Fey will be presenting together at the Oscars (so much for secret presenters), now Donny's let the cat out of the bag.

While taping The Bonnie Hunt Show, Donny Osmond announced that he's doing Dancing With the Stars, the new edition that commences in March.

Oops! See, it wasn't Donny's job to make the announcement. He was supposed to let ABC decide the right time to reveal the lineup of celebrity dancers, although whether they can dance before the show begins is debatable.
