why do people say bullsh!t!

somebody says thats all fake because thats their friends who was in the video..
Javi: Friends of mine are in the commercial.. and the only things that are real are the ninja kicks at 00:18 and 00:48..
all the rest is fake.. I mean, the ball is edited
-- WTF are you talking about then, you fool, stop lying!

but, look at 00:24 on the video i posted, thats a really weird ball position, how can the ball be like that without it falls to the ground?
