[Human]: Do you know if Rafael Nadal has won many matches? [Assistant]: I don't know when he won his latch match, but since he's currently ranked as the number two male tennis player in the world, I'm betting he's won most of them. [Human]: Wow that's awesome! Who are your favorite tennis players? 
I grew up watching Andre Agassi. He's my all-time favorite, but right now I like Roger Federer. he's ranked right behind Nadal, but he's beaten Nadal.
