SEE IT: Billie Jean King rocks vintage afro on ABC series 'Fresh Off the Boat'

It seems the tennis star most likely to compete with Serena Williams these days in terms of spiking media hits is ... the omnipresent Billie Jean King. The 72-year-old retired legend has campaigned tirelessly on Hillary Clinton's behalf in recent times, in person and on social media. Now she was in Tuesday's episode of ABC's "Fresh Off the Boat," a prime-time comedy starring Randall Park and Constance Wu as a married couple from Taiwan having a go at life in America in the 1990s. The show's based on a memoir by Eddie Huang.

The title of the 22-minute saga at hand is "Michael Chang Fever." Billie Jean coaches the lead couple's child, Emery (Forrest Wheeler), as he rises through the ranks of junior tennis. "I'll coach your boy as if he were my own son," she tells Park and Wu's characters, the fictional-yet-autobiographical Huang couple. Though she enjoyed her sitcom experience, King was reportedly out of her "comfort zone, especially with some of the lines in the script."

Perhaps one of those lines was "Let's go, you little puke"?

But there's a reason Billie Jean has stumbled into Florida:

And she gives the audience some "fresh" coiffure in this network-TV appearance.

Hilariously, Wu's fierce-mother character berates a chair umpire, offering him her glasses so as to make line calls and later accosting him, still perched (petrified?) in his high chair. "You have to come down eventually."

From pint-sized series star Ian Chen, the inevitable "grand slam" joke invoking mental wafts of that classic Denny's platter.

Here's a sampling of the best moments from the rest of the episode:

And finally, as the closing credits roll: "Find yourself, Billie Jean!"

That might just be my new on-court exclamation in moments of peril. And as this is tennis, whether you're a top-tier touring pro or a weekend hacker at a local club, there will always be peril.
