Without laughing.
I think I can fuck up a polar bear with bare hands.
I practice MMA for 7 years now, boxing in parallel for 6 years, I could. Not to count strength training at the gym for 4 years, 6ft 1 1/2 for 189 lbs.
I have an insane speed, reflexes similar to my speed. I just have to wait for him to charge me, dodge his attacks, and throw good punches to his head. I won't stop, and at the smallest mistake he does, the polar bear is finished.
