Here's a Groucho Marx line-"a man is dying, and has one last request for his wife, 'honey, I smell coffee cake cooking, can I have a slice?' The wife responds, 'oh, silly, you know the cake is for after the funeral.'".
(or something like that. He said it on the way to Chico Marx's funeral. He said it better.)
Some of my last words could be, "what's the point of outliving all my friends and family if that means there's no one left to brag to? Yes, of course pull the stinken' plug, doc!"
Or, "tell my kids... they could've done better... but all things considered... they weren't half bad."
