I've always been fond of this quote:
"Life does not cease to be funny when someone dies, any more than it ceases to be serious when someone laughs."Some of us are capable of feeling more than one emotion at a time. Life itself is a mix of things, usually simultaneously, including the humorous among the tragic and vice versa. And often "comic relief" is a good release, and helps to cope with the tension.
-- George Bernard Shaw
Yeah, You should have seen the 9/11 live thread...it was hilarious!
