Yes it’s really them. The “kid” is 16 with a very rare disease. All the fist pumping was done in an effort to make Giants fans aware of a fundraiser called “Dynamite: A Keenan Cahill Fundraiser” taking place on May 25. Fans who buy tickets to the game that evening when the Giants take on the Marlins will receive a “Ross is Boss” t-shirt and proceeds from the night’s sales will go to causes important to Cahill and Ross.
Normally I despise youtube sensations like this, but every once in a while something comes out and you have to smile. This was done to promote a fundraiser for sick children, it’s ok to watch it and even enjoy it in my book.
