This animation didn't go quite the way I intended! Harold's dancing is much more awkward here than in real life, but I had only one frame to work with. Getting his legs to bend at the knee was the hardest part.
Harold was simply adorable in A Sailor Made Man, and in fact he really did dance. I never did figure out the scene where the men danced with each other, but maybe it was a sly reference to "those long ocean voyages" where men lost track of their orientation for the duration of the trip.
