Last week's seg attracted just 1.9 million viewers

UPN has shorn “The Mullets.”

The Warner Bros. TV sitcom, which celebrated good ol’ boys and their mullet haircuts of choice (“business in the front, party in the back”) was pulled by the netlet Monday, effective immediately. Tonight’s scheduled episode has been replaced by a repeat of “Girlfriends.”

Critics lambasted the show, but UPN execs had hoped there would be an audience for a half-hour sitcom that played like a live-action cartoon.

But after a decent start, premiering behind “WWE Smackdown,” the show’s viewing levels quickly dropped. Last week’s seg attracted just 1.9 million viewers, making it UPN’s lowest-rated skein.

Six episodes have already aired. The laffer remains in production, however, meaning UPN will have seven more segs of “The Mullets” at its disposal.

UPN says “The Mullets” may even live to see another timeslot. But it’s unlikely the netlet will pick up any additional episodes beyond the initial 13.

“The Mullets” aired Tuesdays at 9:30 p.m.; its lead-in, “Rock Me Baby,” remains on the schedule — but its future also looks cloudy. UPN has yet to greenlight the back nine episodes of that comedy.

UPN has a number of projects waiting in the wings for the Tuesday night slot, including animated entry “Game Over” and the second installment of “America’s Next Top Model.” Repeat episodes of UPN’s Monday night laffers, including “Girlfriends,” “Half & Half,” “Eve” and “The Parkers,” will fill the “Mullets” void for now.

“The Mullets” stars Michael Weaver and David Hornsby as the wrestling-loving, beer-drinkin’ Dwayne and Denny Mullet. John O’Hurley and Loni Anderson also star.

Eric Tannenbaum, Kim Tannenbaum, Bill Oakley and Josh Weinstein produce “The Mullets.”
