Actually, here's some serious advice. If a lion is going for you it tries to bite your throat. Before it can do so, thrust one hand well down its throat then clench your fist. This should start to strangle it. Now, if possible, use your other hand, preferably the thumb, to poke out an eye. The lion will now be desperate to get away from you.
You will have some bad scars, but you will have won. Quite a few people in Kenya owe their lives to this tactic.
Thanks! I'll remember that. Just in case...
Have heard of it used on dogs, and with a dog, you can jam your arm as far back as you can, and it will hurt them. Also, with a dog, if you are being seriously attacked, you can put your other arm around the back of their neck, and then push up hard on the arm that is in its mouth and break the dog's neck.
@Archeus_Lore I wonder if that would work on a Pekinese?
