Ninety Feet of Perfection posted this entry about all the Major leaguers who have appeared on The Simpsons.
The classic, of course, is the first one — Homer at the bat — which features Don Mattingly, Jose Canseco, Darryl Strawberry, Roger Clemens, Ken Griffey Jr., Steve Sax, Ozzie Smith, Wade Boggs, and Mike Scioscia. But other episodes include pop culture references to many others.
I’ve posted a few bits about this topic, linking to one of my favorite — now sadly defunct — podcasts, Extra Hot Great. Then there was the entry that marked to 20th anniversary of the HATB episode. And this one on “Dancin’ Homer” that gives a nod to Lou Gehrig’s famous farewell speech.
