Charlie Sheen may have long ago departed on the train to crazy town, but his legal team is entirely sane and his $100 million lawsuit against former boss Chuck Lorre and production company Warner Brothers has some serious legs -- in addition to being wildly entertaining.

"It is the most hilarious lawsuit I have ever seen written on legal paper," says trial attorney Stacy Schneider, who is betting that Lorre and Warner Bros. will seek to settle quickly rather than continue to allow Sheen to publicly embarrass them.

Warner Brothers claims they fired Sheen because of his lack of moral turpitude. But Sheen's lawyer, Marty Singer, quite aptly points out in his 30-page complaint that they had no trouble with Charlie's morals a few months ago when they signed him to a two year extended contract knowing he was in rehab and on the verge of a conviction for holding a knife to his wife's throat in Aspen.

"There is a legitimacy to his claims. They put up with so much bad behavior in the past that they waive their right to pursue a morality clause when it becomes convenient," says attorney Joey Jackson. "He behaved like a horrific person but he wasn't terminated until he said horrible things about Chuck Lorre and that was his First Amendment right."
