The easiest question ever.
Q.What excites Ab de Villiers?
Ans. 'Anything.'
That's right people. Ab literally gets excited by just about anything on planet Earth. He is one of those people who are able to find happiness in even the smallest of things no matter how irrelevant or the worst of situations.
On his website he says that hes very excited to lead team South Africa. And i am not surprised! for someone getting excited at an early morning breakfast, imagine the excitement of leading your country's national cricket team. Anxious to see how he fares! wait i just came across this tweet by Ab:

" Watched season 4 of Dexter.Love that t.v series!!! blah blah..Great way to relax before a big test series."

 Did u hear that? Ab de Villiers likes Dexter! This is some fucking news!! he likes Dexter. I love Dexter and couldn't possibly imagine someone like Ab liking it! I even ignored the big test series comment (it was against West Indies,duh!)
Ab, you are cool!
