[TOMT] Episode of Daily Show where nobody laughs at Jon Stewart's closing joke.

It was a relatively recent episode (within last 2 months I'd say, probably more recent but my schedule is always blurred) wherein Jon Stewart's (hilarious) closing joke gets very little laughs from the studio audience. Then before the credits he even directly acknowledges the fact that he thought it would generate a better response from the audience.

I remember laughing so hard and wondering why the audience wasn't... I can't believe I don't remember the joke or even the topic.
