The Earth nursery round that Kirk and McCoy try to teach a baffled Spock around a campfire in Yosemite during their shore leave in Star Trek V: The Final Frontier.
Row, Row, Row Your Boat is a traditional Earth round. In Star Trek V: The Final Frontier, set in 2287, Kirk, Spock and McCoy are camping in Yosemite National Park while the new Enterprise-A is being put in order.
After a supper of McCoy's beans, the two humans decide on a singsong and choose the round, explaining to Spock how the parts overlap. Spock fails to come in, having stopped to analyse the words, and observes that life is not a dream.
The song frames the film. Once the encounter with the false god of Sha Ka Ree is over, the three friends return to their campfire and Spock picks out the tune on his Vulcan lyre while the others sing.
