Fred Willard visited Jimmy Fallon’s NBC late night show Thursday, and he and Fallon agreed to pretend he was there to plug his “new” ABC show “Trust Us With Your Life,” which is halfway through its summer order, only Fallon didn’t get the memo.

But, of course, first they had to talk about Willard’s visit to the Tiki Theater – the porn theater in Hollywood at which he was arrested on suspicion of driving with one hand.

“This is the last time I’m going to listen to my wife when she says, ‘Why don’t you go out and see a movie’,” Willard said as he took the guest seat.

Da dum dum!

Willard stuck close to the “the whole thing is a misunderstanding” theme he’s already been working on with authorities. Which doesn’t make for such a great comedy:

“The whole adult theater thing – I thought they were gone. And, I saw this one. It had such a Polynesian look to it, I thought maybe there’s hula dancers in there. Maybe there’s Mai-Tai’s...And I go in and I realize I was the only one awake and sober and conscious in the theater.”

“Do you mind me asking about this?” Fallon then asked.

Fallon – great entertainer. Not much of an interviewer.

Willard continued, not letting Fallon get in the way of his prepared speech:

“Anyway, it was like a trip down Alice in Wonderland – the rabbit hole.”

Then, realizing Fallon was there, he added, “Anyway, fire away.”

Fallon begins trying to turn this into a comedy bit, asking him what was the name of the movie Willard watched at the Tiki Theater, and tossing out non-porn flick names that seem naughty in this conext — names like “Free Willy.”

“No, sadly it was ‘Get Shorty’.” Willard joshed.

“This must be tough,” Fallon said, when that comedy bit curled up and died.

“It’s embarrassing as hell,” Willard agreed. But then remembered his script and sasid, “Nothing happened. I did nothing wrong. Everything’s being sorted out as we speak. I have great respect for authorities – when we need a policeman, god bless them, they’re there.”

Willard was arrested during what has been described as a routine patrol of the place by the police.

“You’re a good man,” Fallon told Willard, adding, “You’re one of my favorites, so you can come to our show and do whatever the heck you want. Except for certain things.”

Then Fallon began to interview Willard about his “new” ABC show. That’s when the comedy really began. Both men agreed to pretend he was there to plug a new show, which turned out to be his ABC sketch comedy series, whic is already well into its run. It’s called “Trust Us With Your Life.” Willard’s the host.

“I want to talk about your new show,” Fallon said. “This sounds like something that’s right up your alley. You’re going to kill it.”

Willard described the show. They showed a clip. The clip was funny. Willard was not in the clip.

“That is genius!” Fallon gushed. “That is going to be a great show!”
