He laughes it off cause he is:
1) nervous Uni is kicking WDW's butt in areas where Disney used to be king
2) sees a shift from WDW to Uni so his business is going to start to hurt
3) is paid by the post despite the lack of content, which explains his one word answers
4) is just a world class idiot and knows nothing of what he tries to talk about, hence the one word WOW posts...
5) can only say WOW cause he has no argument... when you have no argument, and are losing the one you think you are winning, the last resort is just blowing it off, ignoring it, and giving sarcastic, usually immature responses like GO GET DRUNK ON YOUR BUTTERBEER HAHAHA
