Jeeeez Tony, If you are going to provide these videos, you should also provide the alcohol ....
So, if you are being attacked ?, you ask the assailant to stand still ( don't forget to say please ) whilst you find the pressure point, he must also be advised not to kick or punch or bite your finger while you pull on his lip....
I suppose you could give your opponent a stern look :-)
