So true. I got sucker punched one time by a guy who had about 30 pounds on me, and was much taller...
Wrapped him up, caught him with a knee in the chest during the scramble, then left armed guillotine, and I shit you not...he was tapping my leg...like 'aight bruh...I'm good...I'm good...'
I chalk it up as my first and only submission victory. LOL!
