Funny Foursome at Coach House : Comedy: Todd Glass, Ron Robertson, Howard Leff and Larry Wilmore bring their varying brands of humor to San Juan Capistrano tonight.

He may have grown up in Philadelphia, but comedian Todd Glass has become the ultimate Southern California comic.

The Fountain Valley-based comedian has outfitted his Jeep with a folding stage, complete with sound system and simulated comedy-club brick-wall backdrop. He’s done impromptu shows at the beach, and, he says, he has even performed in front of 500 people at a party in San Diego.

He calls himself the “Mobile Comedian.”

“It’s just sort of like a toy,” says Glass of his comedy-on-wheels. “I don’t do it for money. I just do it for the fun.”

The Mobile Comedian will roll up to the Coach House in San Juan Capistrano for a comedy show tonight, but this is a paying gig, so Glass won’t be performing in the parking lot. (He says, however, that he may do a little something in the parking lot after the show).

Glass is sharing the bill with three other comedians: Ron Robertson, Howard Leff and Larry Wilmore.

Those who saw George Carlin at the Coach House last week will be familiar with Robertson, a strong monologuist who pays particular attention to relationships and the differences between the sexes: Picture, as Robertson does, two guys talking about going to the mall with no intention of buying but just to try on clothes. (“Hey, Earl. Wanna go to the mall?”)

“I do a lot of gender-bender stuff, just turning things around,” said Robertson, whose TV credits include “A&E;’s Evening at the Improv,” “Comic Strip Live” and “Caroline’s Comedy Hour.”

Robertson, who began in comedy 11 years ago in Houston, also ponders where men and women meet: “Where do you think Dan and Marilyn Quayle met? Do you think the term ‘last call’ came into play here?”

“Sly, witty and kind of off-the-wall” is how Larry Wilmore describes his character-oriented comedy.

Wilmore, who made five appearances on “Star Search” last year, talks about being black. (One of his best bits is his commercial for a product called Black Away: “One or two drops on your tongue . . . takes the black right out of your voice.”)

But he’s also intrigued by the Orient.

“The Japanese people have over 6,000 symbols in their language,” he says. “That’s a lot of letters. They’ve got to hate playing ‘Wheel of Fortune’ over there.”

Here’s Wilmore on relationships:

“I’m not married because I haven’t found the right person. I was thinking about this, and maybe I’m not the right person. Maybe I’m the wrong person. This could change my whole approach: I’ll have to start looking for the wrong girl.”

Howard Leff does observational comedy with a self-deprecating touch--which is appropriate, given the fact that, as he points out to audiences, he looks like a cross between Gilligan and Norman Bates.

“They realize how goofy I look, so I put it on the table first,” he says.

Leff has another distinction: He says he has never appeared on “A&E;’s Evening at the Improv.”

“I’m one of only about three comics on Earth that hasn’t done that show,” said Leff, who has been on “Comedy Express.”

As for his act, Leff said he does a “whole chunk on different games and stuff--not really sports so much as board games like Monopoly.”

Leff notes, for example, that there is a jail on the Monopoly board, prompting him to ponder: “How much trouble could a hat, a wheelbarrow and a thimble stir up?”

“One of the big things I like to do is try to let people in on my secrets on how to have fun,” he said. “What I really like to do to have fun is bother people at the Home Shopping Network. I’ll call them up, and they’ll go: ‘Hi, can we help you?’

“And I’ll go: ‘No, just looking.’ ”

Todd Glass, Ron Robertson, Howard Leff and Larry Wilmore perform at 9 tonight at the Coach House, 33157 Camino Capistrano, San Juan Capistrano. Tickets: $10. Information: (714) 496-8930.
