The Simpsons Episode 19.06 Little Orphan Millie

Milhouse's re-married parents are accidentally lost at sea during a honeymoon cruise and Milhouse falls into a depression. Figuring he's all alone in the world, he takes on the persona of a cool leather wearing loner, making him popular amongst the school kids.

Jealous of Milhouse's popularity, Bart searches for some living relative who can take care of Milhouse so he can lose his "cool." He tracks down Milhouse's uncle who flies to Springfield and offers to care for Milhouse. Milhouse gratefully accepts, but to Bart's chagrin the girls continue to swoon. It's later announced that Milhouse is leaving Springfield to travel the world with his uncle in a modern flight balloon.

Upon their departure, Bart grabs the balloon's rope to get Milhouse to stay, and is whisked into the air. Six weeks later, with Bart still hanging on, Norbert lands the balloon in the middle of the Chinese Olympic stadium that's under construction.

Among the laborers are Milhouse's parents, paying their debt for being rescued by a Chinese submarine.

Meanwhile, Homer can't remember what color Marge's eyes are, and she vows to never let him see them again until he does. When he recalls a song he wrote when he was younger in which he mentions her eyes, she's so touched that she takes off her shades and reveals that they are a sparkling hazel.
