Question: because your a jackass.
Answers: because your a jackass.
Its because of his teeth, once the braces finish correcting them, he should be able to close his mouth easier and breathe through his nose more. I dont think he wishes to catch flies even though he does some crazy stuff some times. Great show!
Could be the alignment of his jaw bones.
Or maybe it's easier for him to breathe.
if u are the offical zac rollof wouldn't U know??????
