Given the reputation of its star, Charlie Sheen, it should come as no surprise that Two and a Half Men has some dark behind-the-scenes stories (though even shows as seemingly innocent as Seinfeld had their own issues).
Sheen's character Charlie Harper imitated his real-life counterpart fairly closely. Harper was a womanizing, substance-abusing gambler who would eventually meet an untimely death, but it didn't quite capture just how monstrous some of Sheen's alleged actions were. Perhaps even more surprising is costar Jon Cryer's affection for Sheen, which he spoke about at length in his memoir, revealing some pretty shocking things about himself in the process. Somehow, Ashton Kutcher was the most boring dude on the show when he joined the cast in Season 9.
If you still care about one of the most overrated shows of all time, be warned; there are spoilers for the series finale ahead.
