Headscissors in MMA: Sheila Bird headscissor on Kim Couture video

This is an incredible neck-scissor /headscissor that actually causes the girl to be choked unconscious. You don't really see too many headscissors in MMA, but Sheila Bird shows that the power of women's thighs and legs is immense. While males have an upper body strength advantage at times, the lower body strength of women is just unbelievable.
