Just as winter inevitably turns to spring and the swallows inevitably return to San Juan Capistrano, TV dad and dirty comedian Bob Saget has returned to the “Full House” universe. Saget will join the cast of “Fuller House,” a Netflix reboot of the family-friendly series.

John Stamos, a star of the original show and a producer of the reboot, was so excited that he transformed into a typo machine.

“Last but not least-best piece of casting yet,” Stamos tweeted last week. “The great @bobsaget will be joining our show on @netfilx [sic] — this completes the perfect reunon [sic]!”

He quickly apologized for the lapse.

“Oh and REUNION — sorry i’m tired — been a long day — and let’s not be so picky — you want perfect spelling — follow Oprah,” he wrote.

“Fuller House” will focus on the grown-up adventures of D.J. Tanner (Candace Cameron Bure), sister Stephanie (Jodie Sweetin) and pal Kimmy Gibbler (Andrea Barber), who all shack up together in the house D.J. and Steph grew up in. Stamos, as Uncle Jesse, will return for part of the 13-episode run, as will Dave Coulier, a.k.a. Uncle Joey. And don’t forget about Lori Loughlin as Jesse’s better half, Aunt Becky. The bad news: Mary-Kate and Ashley Olsen, who played the adorable Michelle, will sit this one out.

Saget’s involvement was expected, but unconfirmed until now,

“How did you get this information?” Saget, who played D.J. and Steph’s perfect TV dad, jokingly asked Stamos via Twitter.

Though “Full House” helped take the seriously scatalogical Saget from working blue to hosting “America’s Funniest Home Videos,” he had been cagey about returning.

“Not everybody would want to do it. Maybe two-thirds of the cast would want to,” Saget told People last year. “John is such a good guy, and I think he would want it to happen in some way if it could.”

But it seemed there was always room for more “Full House” in Saget’s full heart.

“Just like there’s a place for a movie like The Aristocrats, there’s a place for a show like Full House,” he wrote in his 2014 memoir “Dirty Daddy.” “FH was meant to be able to be watched by everyone. And it relieved some parents from having to actually bring up … their kids’ issues like bullying or drinking at prom. Seeing those subjects covered, however lightly, on FH gave them a point of entry.”
