If Keith Hernandez ever decides to stop calling New York Mets games, he will always have another source of income.

The team's legendary former first baseman became a broadcaster for the team in 1999 and is a multi-time local Emmy winner for his skills on the mic. But after he hung up the cleats, he tested out his acting skills.

Hernandez was one of numerous New York baseball stars to appear on "Seinfeld," playing himself in three episodes. His most famous appearance, though, came in the two-part episode, "The Boyfriend," in 1992, when he becomes a love interest to Elaine despite Kramer's and Newman's grudge against him stemming from a spitting incident on June 14, 1987.

The episode prompted Hernandez's infamous line, "I'm Keith Hernandez." Two documentaries about him have even used the line for the title.

Due to the massive success of the episode, Hernandez still receives some nice residuals.

"It varies, but I can tell you that on an annual basis I’m getting close to $5,000 still. It’s the gift that keeps giving," Hernandez told the "SI Media Podcast." "Remember one thing: I was the guest star."
