Mitch Williams and Lenny Dykstra have a long history of hating each other. Dykstra has long held the belief that Williams blew the 1993 World Series, and seems to hold him accountable for that. Williams, obviously, is not a big fan of that opinion.
The two were able to ... um ... work out some of those issues at a recent event in Philadelphia. The Philly Sports Roast was supposed to be a fun, lighthearted affair. It quickly turned ugly. Be warned, the language in the following video is highly NSFW. Do not watch this at work!
