Boll looks like he is concentrating way too hard in this clip.... His eyes make him look crazy.... hahaha
As for the lyrics, they are pretty simply, just basically saying not to think to much, just work hard and try to get to number 1, winning is the most important, then they introduce their biggest non-Chinese rivals. The part where all the non Chinese players are talking is saying, I love table tennis, I love world championships, and then Boll says, Table tennis, there is no equal on this earth.
