Sing-along

The sing-along was Human ritual around a campfire, frequently after one consumes marshmallows.

Spock, Kirk, and McCoy were camping on shore leave in Yosemite National Park. Spock produced a dispenser of marshmallows, (calling them "marshmellons"), and told the others that after one consumes the treats, one must engage in a ritual known as a sing-along. Kirk and McCoy discussed several songs to sing including Pack Up Your Troubles, Moon over Rigel VII, and Camptown Races before settling on Row, Row, Row Your Boat.
