Actually, I think it was Zach's idea. The first time they went to congratulate each other Phil went for the fist bump and Zach extended his hand.I think it's awesome. They kept things light and had fun with their matches. Leave it to Phil to make himself look goofy intentionally and love every second of it.
I agree.I think it's hilarious because it's Phil. If it was anyone else besides him, it would have been dumb.
