Fox is banking on funnyman and former "SNL" cast member Andy Samberg and "Family Guy" creator Seth MacFarlane to bolster its sagging ratings for the 2013-14 season.

On Monday it released four previews for new comedies aimed at cranking audience laughter all the way to 10. The offerings are: "Brooklyn Nine-Nine," "Dads," "Enlisted" and "Us & Them"

Samberg stars in "Brooklyn Nine-Nine," which Fox is dubbing a "workplace" comedy. Samberg plays a big-shot detective under the watch of a new captain who has "a lot to prove."

"Dads" is MacFarlane's creation (in collaboration with "Ted" cohorts Alec Sulkin and Wellesley Wild) and riffs on the lives of two gaming entrepreneurs (played by Seth Green and Giovanni Ribisi) whose fast and sexy lifestyles get destroyed when their fathers move in with them.

A Florida army base gets the comedic treatment in "Enlisted," which stars Chris Lowell ("Private Practice," "Veronica Mars") and Geoff Stults ("Ben and Kate," "The Finder"). In it an older brother comes home to connect with his two younger siblings and lead a colorful cast of zany recruits.

"Us & Them" wraps up the available trailers and is about a young couple whose love life is constantly interfered with by the family and friends around them.
