So my wife and I are driving along, listening to NPR Science Friday. A caller with a very serious question comes on the air asking about the newly discovered "Rings around Uranus." Silence in the car for a minute or two, then I say to Stacy, "You know, I guess I'm not as mature as I thought I was." She starts laughing, I don't have to explain a thing to her. I'm hitting the big 6-0 this year. Is there hope for my (maybe our) sense of humor to grow-up or am I just doomed to be a 5th-grader forever? BTW, do I have to explain this to anyone?:b And this is a real discovery, click here for further details.
