Governors Ball—New York City’s annual gathering of hot bands, cool foods, and lawn games—hits Randall’s Island in early June. This year’s lineup features Kanye West, The Strokes, competitive cornhole, and this insane milkshake. Understandably, one wants to gird up for such a sensory onslaught.

This year, though, some festivalgoers accidentally overprepared: they put their wristbands on early, and they got trapped.

The wristbands—which, once fastened, cannot be loosened or removed—began shipping out to ticketholders earlier this week. When they show up, there is a certain protocol—you register your number online, you do a brief ceremonial headbang, you put your wristband in a special box in preparation for its deployment—but, as the New York Daily News reports, some people got either overexcited or selfie-happy, and snapped them on right away. Bad idea:

All is not lost. According to the official Festival twitter account, cuffed concertgoers can cut themselves free—and then buy a replacement wristband at will-call for $20. Either that, or they can wear the band forever, like some kind of sweaty talisman.
