laugh now cry later

does comedy come from pain?
some people have such real life basic humor..that doesn't come from a "joke" but born out situations be it embarrassing, painful,symbolic, or whatever..dave chappelles show was one.... all the shit you laughed about secretly or thought about about sayin within "your group" u you laughed because u knew that shit was funny..Kat williams is another one..pimp got some serious mind skills he is the guy in "your group " just waitin for you to say some dumb shit so he can call u out an run with it ..you're embarrassed but u laugh because u know the shit is funny..but my question is why do all the great funny comedians live such tormented lives..is it the stress of having to be funny 24/7 or is it pain that fuels their comedy..theres a long list..belushi..pryor..i could go on..i just wish kat williams all the best and a quick recovery. I just hope "pimp down" isnt a cry for help..as always be famous or infamous fuck being just in between....
