ON NBC, “My Name is Earl” may be a clever, family-friendly show with a witty spiritual message, but it’ll have a raunchier side on DVD.

The bonus features included with the upcoming first-season boxed set will be chock-full of dirty-joke-laden bloopers.

There will even be a mini-pilot episode in which Jason Lee’s character, Earl Hickey, never changes his underhanded, petty-thieving ways.

“I don’t think we said f*** or anything like that, but I definitely don’t think you could air it on television,” says actor Ethan Suplee, who plays Earl’s dimwit brother, Randy.

“It’s the lost pilot . . . it’s just what if things were different. There’s some funky stuff in there. We got to play around a bit with it.”

The bonus episode was shot after the season was done filming, and will bring the total number of episodes on the disc to 25.

Other goodies include a lengthy blooper reel that Suplee wouldn’t even show to his own kids.

“The X-rated blooper reel should be fun,” he says. “Jason and I are pushing for an entire disc of bloopers because I always feel like they don’t put enough in.

“We mess up at least once on every take. At the wrap party, I was terrified and had to get my kids out of there before the gag reel aired, and that was only 13 minutes long.

“Just the language alone is awful.”
