Why does Mike laugh at the Wii?

I'm chillin' w/Ginger keeping my feet warm...and Mike's so proud of his Wii golf skills. He's on stroke 9 for the hole...make that 10...but who's counting?! OK, 11...and he pulled a Happy Gilmore trying to drive off the green. Needless to say, he's now on Stroke 14 and into yet another water hazzard. He was forced to give up. The laughter is maniacal, did I mention that?!
