After Jason reminded me of this, I couldn't believe I forgot it in my trip journal.
On Puerto Rico night, the night of the big ship-wide party they had, Jason got chosen by one of the activity leaders to participate in a male "shake your booty" contest. He was one of six guys who got pulled out of the huge crowd. He didn't make it to the finals, but only because his entourage only consisted of me and the other contestants had posses of friends and relatives cheering them on. (I did cheer loudly enough to get the attention of the emcee, who said, "Did you hear his wife out there shouting, 'That's MY man!' ")
