Kevin Youkilis is notorious for being emotional after strike outs. One time a few years back on a NESN broadcast, they show him sitting there in the dugout after a strike out, and he just randomly screams, "Fuck!" It was flat out blatant. I'll never forget that one as long as I live.
I think during one of the celebrations in '04, a player, I want to say Doug Mientkiewicz but I could be wrong, tells David Ortiz he's "so fucking proud of him" while they hug.
All of this on live TV, folks.
