We can all sleep better now that CBS has sold all the commercial spots for the Super Bowl.

Does anyone recall a Super Bowl that didn't sell out?

The fact that advertisers were lined up to haggle over paying $2.5 million to $3.5 million per 30-second spot is a sign that the economy is on the rebound.

NBC was asking $3 million last year and had to cut rates because the nation was shell-shocked from the collapse of the housing market and the bailouts of Wall Street, automakers and banks.

With an expected 100 million viewers, Sunday's game between the New Orleans Saints and Indianapolis Colts should be the most-watched television broadcast this year.

It's also the Super Bowl of advertising, with more than $200 million being invested by sponsors.

More than 60 commercials will be vying for our attention. According to the pregame hype that's coming in here at Couch Potato Central, this year's crop will be going for laughs.

Here are a few that could be fun:

•Chevy Chase and Beverly D'Angelo as Clark and Ellen Griswold from the "National Lampoon's Vacation" films promote HomeAway, a vacation rental company. Viewers will be directed to a 15-minute online comedy film, "Hotel Hell Vacation."

•Don Rickles provides the voice of some "nasty flowers" for Teleflora.

•Dockers celebrates khakis with 30 men marching in their undies while singing "I Wear No Pants."

•All the Budweiser and Bud Light commercials, totaling five minutes, promise chuckles. Included is a comic nod to ABC's "Lost." The company's trademark Clydesdales may be out this year because its owner, Belgian brewer InBev, is taking the brand in a new direction.

One controversial commercial that is likely to bring the party to a screeching halt for about 30 seconds is the pro-life message from conservative Focus on the Family.

The politically charged commercial featuring University of Florida football hero Tim Tebow and his mother, Pam, may be a heartfelt testimony of their convictions, but will it fit in with all those male-oriented comedy sales pitches?

CBS is opening the door for advocacy ads, and some say the move could be a game-changer for Super Bowl advertising.
