"Homer at the Bat" aired during the third season of The Simpsons way back in early 1992. It's generally mentioned among the series' best episodes ever, but it is without question my own personal favorite.
After making a million dollar bet with a rival nuclear plant owner in Shelbyville over the power plant baseball championship, Mr. Burns decides to stack the Springfield team with ringers from MLB.
When it turns out his initial ringers were all dead, Burns brought in some serious star power in Roger Clemens, Steve Sax, Darryl Strawberry, Wade Boggs and Ken Griffey Jr.—among others.
Except for Strawberry (ironically), each of them befall an unfortunate set of circumstances while in Springfield. Ken Griffey Jr. immediately gets hooked on Mr. Burns' crazy nerve tonic, which was obviously not FDA approved, and ends up with a serious case of gigantism.
But no one has it harder in this episode than poor Don Mattingly, whose sideburns continue to rankle Mr. Burns. After repeated attempts at addressing the unacceptable length of his sideburns, eventually a flustered Mattingly just shaves them ear to ear.
Which gets him booted from the team entirely. He just couldn't win.
To this day I can't even hear Don Mattingly's name without hearing the voice of Mr. Burns in my head screaming, "Maaaaaaaaaaaaatingly! I thought I told you to trim those sideburns!!!"
