The four cast members of Impractical Jokers occupy the top four positions in the show's similarity graph — James Murray at 0.99, Joe Gatto at 0.99, Brian Quinn at 0.98, and Sal Vulcano at 0.98 — a tight cluster that reflects near-total audience overlap between the show and its own cast. That first peak is unusually concentrated. The second peak is where the shape gets more revealing.
Below the cast, the top 10 splits across actors and comedians with no other TV show appearing in the set. Kevin James (0.90) and Adam Sandler (0.88) lead a run of actors whose audiences track closely with the show's, followed by Chad Michael Murray at 0.86. MLB The Show (0.85) is the lone non-celebrity neighbor in the top 10 — a video game franchise — sitting alongside Bert Kreischer (0.85), a comedian, and Maci McKinney (0.85), a reality TV star. Applebee's (0.85) and Rhett & Link (0.85) round out the set, with MythBusters (0.85) the only other TV show in the top 10. The subcategory mix — TV Personalities, Comedians, Actors, one video game franchise, one casual dining brand, one TV show — points to a broad mainstream audience rather than a comedy-specific one, with the cast themselves forming the dominant structural signal.
The two-peak shape here is essentially cast-versus-everyone-else: the show's audience is defined first by its performers, then by a wide mainstream entertainment orbit.
