Honestly, I think it’s enjoyable to see people make prank on other person, not to say that I fully support it but as long as it is not a lame joke and did not defame the victims I suppose that it’s still acceptable by the public.
After all, it will make a difference in his/her day rather than continuously facing normal daily activities which might also made us feel stressed and bored if we do not mix it up with something new, surprising and interesting.
Now, imagine that you are walking a lonely road where everything is 
quiete. Suddenly, you hear footsteps of many peoples who are heading towards you. What would you do next? All of them have furious expression on their face..
The old man that you are going to watch in the beginning of this video acts bravely and continue to walk towards the crowd, even though it’s not often we’ll see people running opposite our way unless disasters such as tsunami occurs.
The others who are still young, as expected ran to ’save their life’. This is why I said old Asian men are the real warriors. 
Go ahead to watch the video, the last prank is very cool and believe me that you’ll be laughing all away untill the end. (Download link is provided)
