Everytime I look in the mirror, I'm reminded of God's sense of humor.
Humor is an extention of happiness. Comedians are those who cultivate humor. Sadly, many of them become crude and still get many laughs, but the crudeness seems to override the happiness.
But yeah, I think God loves humor in us. It's yet another part of his nature manifesting in us. We can pervert it into something else, but ALL good things come from above, and I see humor plays a huge role in that.
If it doesn't then I'm in a heap of trouble. There isn't a day that goes by where I'm not making an attempt at making someone laugh on one level or another.
