Many will remember how Conor McGregor looked at previous weigh ins, almost worryingly thin, but a higher weight class means the fighter can ditch that diet.
When he appeared for his weigh in prior to his fight against Nate Diaz, the Irish champ looked like a beast.
Check out the weigh in below.
From that little exchange with Diaz at the end, it's safe to say Mystic Mac has gotten under his skin.
The fight is due to take place between 4am and 5am tonight Irish time.
