The Chinese have 2 very popular saying about people who argue a lot. Even bent things can be argued back to be straight. Even the dead can be argued back to life. It's more like saying that the person doesn't like to lose in an argument that he keeps coming up with ridiculous arguments. The joke here is they took it too literally with these 2 sayings by showing him training to a point that he could do that.
