Chan Ho Park and Larry King...Gangnam Style!

I've tried my damnest not to post anything Gangnam-style related, but when something like this happens...self imposed rules are meant to be broken.

Alright.  So.  Many.  Questions.

First off, the obvious.  What is Psy doing with Chan Ho Park?  That's an easy one...they're both Korean rap sensations.

Next, what are Larry King and his wife doing with the pair?  And what are the four of them celebrating.

Lastly, and most importantly, where are King's trademark suspenders?
