Watch a wrestler put a 'Figure 4 Leg Lock' on someone and watch that person sceam in agony. Then you put that same hold on someone. There is no pain. Likewise, when the wrestler pushes someones throat against the ropes, it is not the throat that is against the rope, but they are sure to always have one arm over the rope to take the pressure away from the throat. Likewise, if you watch closely, when a wrestler jumps up to stomp down on someones back, leg or arm, watch their other foot. It always lands first on the mat, thus minimizing the pressure to their opponent. Headlocks, arm locks, and the such are only moves that give the wrestlers time to catch their breath, they do absolutely no harm. Head butts are also so fake, as they only do a headbutt against their own hand and butt their hand on their oponents head. If you were to smack your head against someone elses head, you would crack boths heads open.
Go ahead and put John Cena's submission hold, the SPF or whatever on someone. Again, it causes no pain. The sleeper hold is probably the most fake of all the holds. Have you noticed that a few wrestlers still try and do this move, but nobody falls asleep anymore? In the old days, just a few seconds of the sleeper hold would have any wrestler on the mat fast asleep, (besides the audience).
