On the latest episode of “Hiking With Kevin”, the host takes a stroll through a Malibu canyon with the former “Everybody Loves Raymond” actor.

During the hike, the Nealon recalls an incident in which he and Garrett pretended to be air conditioner repairmen after the receptionist at a club didn’t realize they were comedians.

“We show up and the receptionist at the club didn’t recognize us,” the former star of Global’s “Saturday Night Live” says. “She goes, ‘are you guys here to fix the air conditioning?’ We went right into the mode of AC repairmen and started checking out the ceiling, we took down the panels, we were talking about ducts and having great placed ducts. We stood up on her desk right in front of her”

Garrett add, “You told me to go to the truck and get the ladder.” Nealon continued, “I tell her listen, we’re gonna have to shut down the club for two days. She goes, ‘no no, we can’t do that we have shows tonight.’ We said, who’s playing? She goes ‘Kevin Nielson and Brad Guerette.’ I said, I’ve never heard of them, nobody will come to that show. Finally we told her who we were. She was totally embarrassed.”

The duo also talk about everything from opening for Frank Sinatra to performing on “Star Search”.
