I'm not of the 'funerals should be sad' group of believers.  
Funerals are for the living - and at worst, should be a reflection of the joys of someone's time on this planet. 
I've been to some really wonderful celebrations of life / memorial services.  I have a lot of funny, odd little memories of hamburger's brother's memorial service.
My uncle (hamburger's older brother) was very active in the union movement in my hometown.  The unions were well-represented at the memorial.  A union rep was one of the speakers.  There was a great deal of puzzlement and whispering when hamburger got up to speak and began with, "My brother ... ".   From behind, and beside, me I could hear "What union local is he with?" 
There was of course lots of mingling and mixing - I spent some time speaking with childhood friends who I hadn't seen in 20+ years.  On preparing to leave, A. came to me, gave me a hug and said, with a big bright smile,  "We need to get together like this more often."   
 
 
My uncle's widow hosted a rather pleasant dinner a bit later on.  It was at a nice local restaurant, the beverages flowed freely, the jokes and laughter were plentiful.  It was truly my uncle's kind of evening, and that evening is part of the wonderful memories I have of him.  It seemed as if we were having a party on his tab, and he was there with us, having a good time again.
