The Buffalo Wild Wings Blazin' Challenge.
For USA Today, Gronk participated in the feat, which traditionally consists of competitors downing a dozen of the franchise's hottest wings in under six minutes. The sauce is so hot, participants have to sign a waiver before competing.
Things gets messy (like, really messy), but he made it.
Just don't accuse him of crying.
