‘Rick and Morty’s Spencer Grammer Wants to Join ‘The Simpsons’ as Sideshow Bob’s Nepo Baby

If years of absorbing full-body rake blows haven't rendered Sideshow Bob infertile, Spencer Grammer has a story idea for The Simpsons. 

Grammer, of course, is the voice actress behind Rick and Morty’s Summer Smith. She also happens to be the daughter of Kelsey Grammer, who, when he’s not busy making awkward Frasier-themed commercials, voices Bart Simpson’s archenemy, Robert Underdunk Terwilliger.

Spencer Grammer recently guested on Nancy Cartwright’s Simpsons Declassified podcast, where she proposed a way that she might join the cast of the long-running Fox show. 

“I secretly wish that Sideshow Bob had a daughter, and that I got to play his daughter,” Grammer told Cartwright. “And she enacts revenge for all of the years that he left to pursue killing Bart, because she’s so angry that she was abandoned, and he was just obsessed with this guy Bart.”

In Grammer's pitch, Sideshow Bob’s daughter, enraged over her father’s fixation on another kid, ends up trying to kill Bart herself. “That’s my dream,” Grammer added, pointing out that it’s a “super nepo baby” idea. “Like fully immersed in the nepo baby,” she added. 

“Spencer, I think we should meet again after this podcast,” a visibly impressed Cartwright responded.

When pressed for more details, Grammer explained that Sideshow Bob’s daughter should be “slightly older than Bart, basically the same age as Summer, like 17. So he could maybe have a crush on her, you know?” She also suggested that the character could be named “Sabrina” as a nod to Cartwright’s niece, Sabrina Carpenter. Cartwright put forward “Bobbi” as another possibility.

The Simpsons has explored stories about the fruit of Sideshow Bob’s loins in the past. Back in season 17’s “The Italian Bob,” we learned that Krutsty’s former sidekick started a family, including a son, little Gino Terwilliger.

But after the character appeared in just two episodes, the Simpsons writers seem to have largely forgotten about little Gino. Plus, hiring Grammer to play Sideshow Bob’s daughter would make a lot of sense, not just because she’s a talented voice actress herself, but because The Simpsons has a long history of stunt casting Bob’s family members.

Finally, given that Spencer Grammer was estranged from her father between the ages of 4 and 16, her pitch about Sideshow Bob’s murderous impulses leading to childhood abandonment might be somewhat personal.
