The funny part is, a day or two before he posted it, I tweeted him, inviting him to take the challenge "on behalf of all women everywhere." But it looks like someone else also challenged him (he mentions a name in the beginning of the first vid.)
Mouse - thanks for the clarification. I *think* he has a youtube - he's posted a couple of his son's school projects before (one modern take on a biblical story and one Rube Goldberg machine). So I'm not really sure why he picked instagram for this video.
