Watch The 30 Most Brutal Knockouts of All Time in One Glorious Video

OUCH.

If 2016 left you feeling extra punchy, Showtime Sports has helpfully compiled a supercut of the 30 greatest knockouts in the history of Showtime Championship Boxing. 

It’s predictably brutal stuff, with many KOs harkening back to a bygone era when the cult sport of boxing was still a very big deal, and the UFC had yet to claim the combat sports throne. 

Some standouts in the video include Mike Tyson destroying Frans Botha in 1999, Evander Holyfield toppling Tyson’s conquerer Buster Douglas in 1990, Kostya Tszyu starching an undefeated Zab Judah in 2001 and more recent contenders, like current heavyweight champ Deontay Wilder (above) wrecking Artur Szpilka in January 2016. 

Watch the video above, and then maybe pop a few Advil afterwards if your head is still ringing.
