Betty Lou wants to be an astronaut, Grover wants to be a policeman, Bert and Ernie choose forest rangers. Telly Monster wants to be a baseball player, although the Count counts 700 strikes before Telly hits the ball. Cookie Monster wants to be a cook, and open the world's first drive-in cookie restaurant. Elmo starts out wanting to be a cowboy, but as he sees everyone else's choices, he wants to be everything at once.
Oscar the Grouch refuses to participate, claiming that he thought the theme was "When I Throw Up". Grundgetta ropes Oscar into her ballet act, fitting a tutu around his trash can and performing a dance from "The Nutcracker" with her unwilling partner. 
Big Bird is so busy helping others that he doesn't have time to choose a job. In the end, Prairie Dawn makes Big Bird the director.
The show was revived in 2007 as When Elmo Grows Up.

In May 2001, this show was performed in the Netherlands for Sesamstraat's 25th anniversary, as Als Ik Later Groot Ben. A few changes were made: Telly was featured as a soccer player instead of a baseball player (since soccer is played more often in The Netherlands), and Pino made a couple of introductions.
