Funny took a back seat to explosions and robotic mayhem in the latest weekend North American box office results, according to studio estimates.

A pair of new comedies starring Jennifer Aniston and Kevin James were simply no match for the action/adventure juggernaut that is Michael Bay's Transformers: Dark of the Moon.

Transformers: Dark of the Moon remained atop the U.S. box office for the second straight weekend, grossing $47 million. The film, which stars Shia Labeouf and Rosie Huntington-Whitely has now earned a total gross of $261 million. The film had an estimated $195

Horrible Bosses, debuting this weekend, was in second with $28.1 million.

Zookeper, also new to theaters, came in third with $21 million.

Disney's Cars 2 at $15.2 million and Bad Teacher at $9 million rounded out the top five.

The rest of the top 10 includes Larry Crowne, Super 8, Monte Carlo, Green Lantern, and Mr. Bopper's Penguins.
