Mike,
Don't let it sadden you...
Be Glad, be happy that you shared those times with others in your life, be elated that you experienced good times and share memories from those times..
Don't think it's gone and never gonna happen again. Await expectantly the next one to provide laughter and smiles...
I am sure Dick Martin would have wanted people to dance joyously around his coffin, rather than hang their heads and be saddened.
For me, I want to go screeching in at the last second, all completely used up, exclaiming "Whoohooh, What a Ride"..
