Sheeba (Homer vs. Dignity)

Sheeba is a panther and an imaginary attack animal belonging to Homer Simpson.

History
When Marge told Homer that they needed to talk to a financial planner, Homer misheard it as "financial panther" and drifted into a fantasy where he was in a bank lobby and a snobbish banker told Homer that his account was a dollar overdrawn. At that, Homer gestured off screen and said, "Get 'im, Sheeba!" The panther then leaped into the lobby and savagely mauled the banker while Homer laughed.

When Homer returned to reality, he was still chuckling at the imaginary scene. He then told Marge, "I'm on board."
