Iceberg art

*WARNING: EDUCATIONAL CONTENT

Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form. When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.

So enjoy them while you can; pretty soon global warming (que dramatic scary music and people creaming) will render images like these a thing of the past.

    Really stunning photographs, God knows I hate the cold but that's almost an incentive to see it in person.

Commanding Officer sacked

It seems that men in high places still haven't learned to keep their dorks zipped up. Capt. Scott Bawden, Commodore of Submarine Squadron 17 in Bangor, WA, was relieved of commnad after having "lost the confidence" of his boss. If you follow submarine news you will remember that Bawden was the Commodore who axed some of the crew of the USS Columbia after a hazing incident. /hat tip The Stupid Shall be Punished What comes around goes around? It has been quoted by a Chief who knew Bawden that morale will probably get better now that Bawden has been shitcanned. Sounds like a few Commodores I know. But there is more to this story than a guy who perhaps can't do his job anymore. Bawden was busted sleeping with someone elses wife, a Chief's wife, no less, IN HIS OWN command. Will the top brass save a onetime fair-haired boy's career, or will he end up "walking the plank?" What a jackass. It's bad enough that the Officers screw the enlisted, but ...

wtf, over....

Bernie Mac died at age 50 the other day, Isaac Hayes died today at 65. I guess show business can be rough. Only the good die young. - Billy Joel I didn't listen to Bernie Mac's stand up except for maybe a few minutes as I was channel surfing. He was playing in Vegas a few weeks ago when I went for the weekend with my wife. I have posted about Isaac Hayes when he decided to leave South Park after the creators dogged the stupidity that is Scientology. Hayes didn't seem to have a problem when Matt Stone and Trey Parker made fun of all the other world religions. I didn't read the story about Hayes but I can only guess he didn't die by falling off a suspended bridge while on fire, only to fall off and become impaled on a pointy rock, and then mauled apart by a hungry bear and mountain lion- then ending in a violent release of his bowels. Cosmically ironic if it did though. On top of these weekend deaths, visitors to the 2008 Olympics in Beijing have been murdered. The fa...

Stop it already with the dumb baby names...

My wife received a Christmas card from an old "Knottie" friend and it has been begging for a post on my blog. About 6 months ago this person told everyone (on The Knot*) she had the perfect name for her unborn girl, a name she kept a secret so nobody would steal it and use it for their own. The whole ordeal reminds me of the Seinfeld episode where George Castanza had the perfect name for his future kid and, in a moment of weakness, revealed the name to an expecting couple who then stole the name. Do you remember the name? Seven, like the number. So the months went by and after the birth of her child she unveiled the name to everyone on The Knot while the umbilical cord was still attached. Before I tell you the name of her baby girl I must tell you that the name wasn't as bad as some of the celebrity names that these idiots came up with. Here is a short list: Moxie Crimefighter Jilette Pilot Inspektor Kal-el Coppola Cage Apple Blythe Alison Martin Sonnet, True, Autumn, ...
