AlthoughThe Simpsonsseason 36 saw Milhouse’s original voice actor Pamela Hayden retire from the role, the show’s Disney+ special involved one final surprise secret cameo from her original version of the character.The Simpsonshas been on the air for a long, long time. The show is officially the longest-running scripted primetime American TV show in history, so it is no surprise to learn that some of its original voice cast are aging out of their roles. Still, the fact thatThe Simpsonsseason 37won’t feature Pamela Hayden’s original Milhouse remains a surprise.

Hayden voiced Milhouse throughout the first 36 seasons ofThe Simpsonsbut retired from the role in November 2024. It is not yet clear whether Milhouse, Bart’s bully Jimbo, and the other characters Hayden plays will be recast or retired. However, it is clear that the Milhouse seen in classicepisodes ofThe Simpsonslike “Bart Sells His Soul”will not appear in the series anymore, which is a striking surprise considering how rarely the show kills off characters for good.

Hayden Retired From Her Iconic Supporting Role In Late 2024

As such, I was delighted to discover that Hayden’s Milhouse made one last secret appearance inDisney+’sThe Simpsonsseason 36 special “The Past and the Furious”months after announcing her retirement. The special mostly focuses on Lisa, who has become depressed and despondent because nothing will grow in the concrete wasteland of Springfield. Lisa knows that this environmental destruction was caused by the ruthless industrialist Mr. Burns, but feels powerless to stop him. That is until a therapist’s clickers puts her in a trance and sends her back in time to the 1920s.

Eventually, Lisa desperately tries to travel back to the past again to fix the timeline but can’t access her missing clickers.Milhouse attempts to help Lisa out in “The Past and the Furious” but fails, in what feels like a fitting sendoff for Hayden’s enteral sad sack supporting character.

Why Milhouse’s Final Scene In “The Past and the Furious” Is The Perfect Send-Off For The Character

Milhouse’s Final Attempts To Woo Lisa Were As Tragically Funny As Ever

According toIMDb, Hayden plays Milhouse in “The Past and the Furious” although she announced her retirement before the episode aired. However, as evidenced byThe Simpsonsseason 36’s clever acknowledgmentof the show’s internal inconsistencies,“The Past and the Furious” may not technically count as Milhouse’s final appearance. The Disney+ special took place in an alternate reality, meaning his final canon appearance was in the streaming service’s Christmas special “O C’Mon All Ye Faithful," released in December 2024. There, Milhouse aided Bart in a bizarre but ultimately well-meaning prank on Ned Flanders.

Bob’s Burgers Season 15, Episode 10 Highlights Its Advantage Over The Simpsons Season 36

Bob’s Burgers season 15 episode 10 highlights the bizarre reality that the sitcom pulls off The Simpsons' old formula better than The Simpsons itself.

However, it was still fitting that Milhouse spent his cameo attempting to impress Lisa with all the gadgets he got from the countless therapists he attended. Naturally, he didn’t have the one Lisa needed, which made this sad display even more comically tragic. Although it was a short scene, the moment paid off a storyline that Hayden’s character had been trapped in for decades. Milhouse spent years trying to woo Lisa and even married her in some of the show’s versions of her future. Although he failed here, the show repeatedly proved he never stops trying in every version of reality.

Can Hayden & Milhouse Still Return In The Simpsons?

Hayden’s Iconic Character Can’t Simply Be Forgotten

WhileThe Simpsonsseason 36’s special was sadderthan viewers might have anticipated,Milhouse’s cameo was a perfect tragicomic sendoff for Hayden’s version of the character. Of course, this leads viewers to wonder whether Hayden can still return as Milhouse in future outings. Although the actor can as long as she is still alive, this is unlikely to happen since she publicly announced her retirement. However, the question of whether Milhouse can still return without Hayden is trickier.

The Simpsonsneeds to replace Hayden’s original version of Milhouse but, paradoxically, her perfect final appearance as the character proves just how hard that will be to pull off.

The Simpsonswill still need Bart’s best friend even after Hayden’s retirement, so it seems likely that he will be recast. It will be tough for the show to find a new version of Milhouse, but the longevity ofThe Simpsonsmakes it unlikely that the show will retire the character due to this difficulty. Some ofthe funniest moments inThe Simpsonshave come from Milhouse, whose luckless nature and excessive caution were always placed in stark contrast with Bart’s feckless attitude. As such,The Simpsonsneeds to replace Hayden’s original version of Milhouse but, paradoxically, her perfect final appearance as the character proves just how hard that will be to pull off.
