Megan Mullally's top 10 neighbors form a tight, undifferentiated band — scores run from 0.90 down to 0.86 with no single dominant pull and no sharp drop-off. The cluster is built almost entirely from two subcategories: Actors and Comedians, with one TV Personality and one musician rounding out the set.
Tallying the top 10: six are Actors (Sean Hayes at 0.90, Jane Lynch at 0.88, Elizabeth Banks at 0.87, Neil Patrick Harris at 0.87, Colin Hanks at 0.87, Zach Braff at 0.87), one is a Comedian (Patton Oswalt at 0.89), one is a TV Personality (Joel McHale at 0.87), and one is a Musician (Josh Groban at 0.87). The tenth neighbor, Max Greenfield, is also an Actor at 0.86. Mullally herself is an Actor, so the top 10 is predominantly same-kind — actors and comedians whose audiences look structurally alike — with no TV Shows, brands, or other categories breaking through in the top 10.
The flat shape here signals an audience that doesn't cluster tightly around any single adjacent figure; instead, it spreads evenly across a broad swath of comedy-adjacent television talent, suggesting a generalist audience comfortable across the actor-comedian spectrum.
