Scott Baio has made it clear he isn't exactly thrilled about the upcoming Happy Days reunion. As ET Canada shares, the actor took to Twitter on Monday to express his feelings towards the event, which he won't be taking part in.

Baio says reunion promotes "anti-American socialist"

Baio— who played "Chachi Arcola" on Happy Days— isn't pleased with the reunion because of its political leanings. Since he himself is a Republican, he doesn't agree with the cast of the '80s sitcom coming together to show support for the Democratic party of Wisconsin. 

That's why Baio responded to Ron Howard's tweet announcing the event, expressing his personal disappointment in its purpose. "What a shame to use a classic show like Happy Days about Americana to promote an anti-American socialist. #Shameful," he tweeted.

Scott Baio arrives at Nickelodeon's 2012 TeenNick HALO Awards on November 17, 2012.

Baio unimpressed with John Stamos for wanting his role

Baio also fired back at John Stamos for his tweet in response to Howard, where he asked if he could take over Baio's role for the reunion! "Can I play Chachi?" Stamos had inquired, knowing that Baio would be absent. 

The original "Chachi" wasn't impressed by this, firing back at Stamos' request. "This is what Hollywood has come to," Baio tweeted in response to the actor, including the hashtags "#shameful" and "#LiberalsAreDesperate."

Baio calls his character "the original Wah Wah Wah"

Baio also responded to a fan on Twitter who reassured him that he "could never be replaced" in the role following Stamos' tweet. "The original Wah Wah Wah!" he wrote back, including a thumbs-up emoji. "Thanks." 

As ET Canada mentions, Baio's Happy Days character "Chachi" went on to have his own spinoff series, called Joani Loves Chachi. However, the show was unsuccessful and short-lived, only lasting from 1982 to 1983.

The Happy Days reunion is the latest virtual cast reunion for a cause to be announced. Set to take place on Sunday, it will see Henry Winkler, Don Most, Anson Williams, and Marion Ross— as well as writer Lowell Ganz— reuniting for the first time in years. American fans who are interested in watching the one-time only livestream can access it by donating to the Democratic party of Wisconsin!
