Air date: 10/31/1993

Rocko unfortunately loses his job at the mega comic store, and decides to take up several different jobs that, well, he obviously doesn't enjoy. One includes working as an explicit hotline operator.

By the end of the episode, he ends up getting a job at the local comic book store, returning to the job environment he belongs in. You're not the exception to the rule. It's important to realize that you're going to have to do jobs that you don't necessarily want to do. But hopefully they'll pay off in the long run.
