HBO's "Silicon Valley" is known for skewering the Bay Area tech industry with its biting, so-true-it-hurts style of satire, and it has gained a following among the same tech groups it makes fun of each week.

So it's not much of a surprise when reality mixes in with the fictional TV show, especially in the form of real-world personalities appearing as part of the Silicon Valley on "Silicon Valley."

The latest in a string of cameos on the show is none other than San Jose Mayor Sam Liccardo, who recently shared photos of himself on set with members of the cast.

"I'm not quitting my day job, but I had a great time jumping in with the cast and crew for a (very brief) cameo on HBO's Silicon Valley," Liccardo wrote in a Facebook post with the photos.

"... and yes, I'm the only guy wearing a tie," he added.

Liccardo shared the photo to Twitter as well, shouting out showrunner Mike Judge and the show's support of San Jose Promise, which supports low-income San Jose high school graduates and provides them with up to two years of free community college, among its other programs.

The San Jose mayor also took time to praise San Jose local Kausar Mohammed for her role on the show, mentioning her alma mater (Evergreen Valley High) and encouraged people to "remember her name as we watch her star rise in Hollywood!"

It's not clear whether Liccardo is playing himself in the cameo — although there's a pretty lengthy list of SV folks who've played themselves on the show — but he did reveal that his appearance will be on episode one of the show's sixth and final season.

The last season of "Silicon Valley" is expected to premiere in late 2019.
