Jake "The Problem Child" Paul is ready to make good on his promise from a night ago. After his opponent, Mike Tyson, slapped the former YouTuber at their weigh-in, Paul told viewers "[Tyson] must die.

While Tyson walked up to the scale, Paul got on his hands and knees and started crawling over to his opponent. The controversial YouTuber — who was wearing shoes at the time — then stepped on Tyson’s bare toes while getting all up in the boxing legend’s face.

As Tyson, who weighed in last, made his way across the stage, Paul crawled toward him on all fours. After Paul rose to his feet to stand nose to nose with the 58-year-old boxing icon, Tyson slapped Paul in the face with his right hand.
