This made me a laugh, with regards to John Danaher's dedication to BJJ..
Renzo Gracie had to say about Danaher’s behaviour: “he (Danaher) does jiu-jitsu every day; we can’t get him out of here. I think he would come in on Christmas if we would let him.”
.
If they're all as hilarious as the quote in the OP we're in for a great thread. 
"There's more philosophy on jiu-jitsu mats than any ivy league school in America."
"The secret of this sport is, while you're the nail, hang in there. Let them hit you until the day you become the hammer, then you smash them back!"
" I just gave him the old style Raccoon, it has been a while since the last time I did."
"that was a mistake mine"
