LOS ANGELES – A newly commissioned analysis by the Institute for Retrospective Cultural Significance has revealed that the attendance figures for Nirvana's legendary May 29, 1991, gig at Jabberjaw coffeehouse have expanded to include every single person who has ever resided in Los Angeles County. The infamous last-minute show, where the band allegedly debuted "Smells Like Teen Spirit" to a "star-studded crowd," now boasts an estimated 10 million retroactive attendees, vastly outnumbering the venue's actual 40-person capacity.

"It's a phenomenon we call 'Fame Contagion,' " stated Dr. Eleanor Vance, lead researcher at the Institute for Aspirational Proximity Studies, whose findings were released today. "Initially, maybe three dozen people were actually present – mostly unemployed scenester types, a few record store clerks, and a couple of bewildered tourists who had wandered in looking for decaf. Now, every single Silicon Valley tech bro, reality TV star, and even a few sitting senators will proudly tell you they were 'right at the front, man, totally knew they were gonna be huge.' " Dr. Vance noted that geological core samples taken from the Jabberjaw site indicate the maximum physical occupancy of the space in 1991 was closer to 37 individuals, 12 of whom were already heavily sedated before the first chord was struck. The study also highlighted a statistically significant correlation between current personal net worth and the vividness of alleged Jabberjaw memories.

Local man Chad "The Oracle" Jenkins, 54, now a prominent crypto investor, vividly recounts his experience. "I was there, dude. Right there. I remember thinking, 'These guys are gonna change everything.' Though, to be fair, I thought that about every single band that played Jabberjaw between '89 and '93. My main goal that night was honestly just to get my 'zines to sell before my girlfriend broke up with me again." Conversely, retired barista Brenda Periwinkle, 78, who actually served coffee to the band that night, offered a different perspective. "Nirvana? Was that the loud one? I think I told them to turn it down, or at least play something I could clean to. Honestly, the biggest 'star' I remember seeing that night was my landlord, who cornered me by the bathroom to shake me down for overdue rent.

The retrospective attendance boom has led to property developers in the area planning a "Jabberjaw Experience" theme park, complete with holographic Kurt Cobain and an interactive exhibit where visitors can convincingly pretend they were "totally there, even if they were five years old and living in Ohio at the time." Advance tickets are already selling out, primarily to people who are certain they saw the original show.

The Institute projects that by 2030, the number of claimed attendees will exceed Earth's current population, proving that the only thing more powerful than a legendary rock band is the collective human need to pretend you were part of something important.
