It's hard to find the right words to say when a close friend passes away.

It's even harder to honor them with a masterful speech about life, love, purpose, and friendship.

Unbeknownst to many of us, Billy Crystal and Muhammad Ali share a friendship that spans all the way back to the 1970's. On stage at his friends eulogy, Crystal shares stories about the two sharing memories on stage, in private, and even coming up with touching nicknames for each other.

I know I don't have near the capacity for words that Billy Crystal does, and I don't want to take away from his exquisite tribute to his life-long friend. Take 15 minutes out of your day and watch his speech. If you've ever had a true friend in life, it's not just Ali that Billy Crystal is talking about.
