It was the flimsiest of excuses to get naked. All I heard was "I'm a boring lawyer with a dull pointless life. Sure would be fun to get naked. Hey, that sounds like an excuse to get naked." Just looked stupid.
I'm all for the nakedness, just think they looked a little silly pretending that was a reason. I prefer candor myself: "Hey, wanna do it naked!" would have endeared them to me.
It's kind of a weird exhibitionism, too: naked on national TV except you know you're not. Sort of pretend naked for the home audience. Naked in front of a dozen people who will probably see most or all of you cleaning up in the river anyway. (And running around in wet boxers doesn't leave much to the imagination. We got a much better look at what they were packing with their short on.)
The whole thing just came off as a ballsy move without a lot of balls. Just a missed opportunity.
(But I did enjoy watching Dimples' reaction. I kept imagining those things getting caught on thorny branches though, or wrung into an axle, and I won't be able to shower with my clothes off for a week.)
