Yes. That's J.R. Ewing in lederhosen. He never could resist a hat, be it cowboy or loden hut.
We could almost forgive Larry Hagman for this getup. He's in Germany for Oktoberfest, the beer festival immortalized in such film classics as Beerfest and Oktoberfest, and when in Rome...or Munich, right? Plus, he's the beloved Major Anthony Nelson from I Dream of Jeannie!
However, as you can see, the nether regions of his short pants appear to have a couple of openings. And he's using that area as a hand warmer, in a way that is similar to the device ladies use called a muff.
If he's doing what we think he's doing, we're surprised he doesn't look happier. Also, we hope he washes his hands before eating.
