Ross Brockley is writing an extra 20 jokes just in case any of the first 100 don’t pan out.

The Lincoln comedian/actor/filmmaker known for playing the thirtysomething slacker in the Holiday Inn commercials is offering a money-back guarantee on his “Night of 100 Laughs” tonight at the DelRay Ballroom.

If he can’t generate 100 chuckles, snorts, guffaws, etc., he promises he’ll give patrons their $8 back.

Yes, he really plans to count.

A word of warning, though: He has three hours, and there will be alcohol available.

He also has nothing to lose … well, nothing but all the money.

 “I’ll do whatever it takes,” he said. “We’ll see how it goes. I’m feeling good about the last 20 (jokes).”

Brockley turns 40 on Wednesday, and the gig is sort of a gift to himself and Lincoln.

He hasn’t performed standup in his hometown since appearing as a special guest at a local comedy show in the summer of 2003.

In fact, he said, it’s been awhile since he’s stepped on a stage anywhere. He performed last spring at a club in Salt Lake City, where he was filming an independent movie.

Before that he did “a little something” in New York City.

“I wish I did it more,” he said.

That’s why tonight’s show packs a little drama.

It also will be the longest show he’s ever done.

“I’m looking forward to it,” he said. “I’ve always wanted to do a bigger show, but I never felt like I was ready to do it.

“It should be worth the price of admission to see if I can’t get to 100 (laughs).”

Brockley has become quite visible of late. Tonight’s show comes on the heels of his last film release, “Down and Derby.” He had a supporting role in the family comedy about the Pinewood Derby, which starred Greg Germann (“Ally McBeal”), Lauren Holly and the late Pat Morita.

Another movie, the independent Mormon film “Church Ball,” comes out later this year. The movie is about ultra-competitive church basketball teams and stars Fred Willard and Andrew Wilson — Owen and Luke’s older brother.

Currently, Brockley’s been working on his Denton farm, tending to his chickens.

He has a couple of his own film projects in the works. And he’s been preparing for his standup show, which will feature all new material.

“To tell you the truth I’ve never told any of these jokes before,” he said. “We’ll see how they fly.”
