Complete foolishness, but every region has its own customs and games. For example, in North Africa, there is the 'sheep fight,' where they bring two rams to butt heads against each other, and the winner earns money. and some people even bet on the winner..
This is serious, even though they place a bet on them. However, things are really happening in some countries you can imagine the confident that people have on this rams. Honestly, this is quite annoying to me because I have never seen such thing in my country, although just like as you mentioned that is how it goes because we all have different ways we do things, so is quite a normal thing that we can never change.People are actually using Rams to fight against each other for an entertainment purpose, but this is no more common as before, as many things have developed and also changed, but the sad aspect of this is from the way we make use of this animals in fighting each other, which is not polite enough, I've witnessed a situation were by the rams are fighting and as they nod each other, one died immediately, because of the level it was being hitter by the other one.
