I think I like 'em all! :D
But, if I had to choose, it would be any from my little girl, especially when she says I'm the best Mom in the world (not that she has all that much to compare me with).
How about best backhanded compliment?

My (then) honey once said, "Your as good as a $5,000.00 a night call girl".
My response: "Thanks? I think? And how would *you* know, anyway????"
