Caption This 40

Please name this photo [See below for details]
London, ON, October 2007

When our son had his green cast (click here and here for earlier photos/entries) replaced with an orange one, I thought we should remember the moment. The new cast is much lighter than the old one and can serve double duty as a runway marker at the airport. Unlike the casts of my youth, which were icky, heavy and (at least initially) white plaster, Zach's is made of a svelte, colorful fiberglass wrap. Of course, no one aspires to actually have a cast. But if you've got to have one, technology makes it a little less onerous these days.

But can you come up with a caption for this photo? Hope so...

Your turn: Click on the Comments link below and share a caption or seven. Zach's agreed to help me sift through the suggestions this week, and we'll jointly post the winner next week. So vote now, vote often, and have fun with it. New to Caption This? Click here for instructions.

About last week's image: A simple picture of a blue balloon prompted some incredibly funny suggestions. BreadBox took it with this winner: "Is it an innie? Or an outie? You be the judge!" I smiled for a while after reading it.

And since I'm really bad at picking just one, I wanted to share some other worthy mentions:

• Gyrobo: "The Reproductive Cycle of the Common Balloon -- Part IV"
• David: "Clara the face painting clown exhaled deeply into the large blue balloon, and then tied the knot, with herself inside! Quite a trick."
• Susan Helene Gottfried: "Bellybuttons are people, too!"
• Melissa: "Well, how long can you hold your breath?"
• Shane: "Tijuana Breast Implant Surgery, 25 bucks. Cost of Implants, 50 cents. The expression of her soon-to-be-deflated ego, priceless."
• Jessica Foster: "As he continued to travel over the tree tops, Winnie the Poo said, "Oh bother, perhaps this wasn't the best idea...."
• Snaggle Tooth: "Any one got a pin?"
• Sister AE: "A smurf belly-button, unretouched."

Have a good time with this week's Caption This. And thanks again for playing along!

One more thing: 60 years ago today, Chuck Yeager climbed into the X-1 and became the first person to break the sound barrier. Supersonic flight is one of those technological milestones that, like the invention of the integrated circuit, radio transmission and the internal combustion engine, is easy for us to overlook. But I can't help but think that moments like this, and the people with the brains and the guts to make them happen, change our world. And, by extension, us. Thanks, Mr. Yeager.
