Even though Charlie Sheen's beloved character Charlie Harper died on the CBS sitcom 'Two and a Half Men' in season 9, many fans were expecting the controversial actor to make a surprise return on Thursday night (Feb 19th) as the show aired its final episode, but he was nowhere to be seen.

Sheen, who was famously fired from 'Two and a Half Men' back in 2011 by its creator Chuck Lorre, was eventually replaced by Ashton Kutcher's character Walden Schmidt for season 10, has hinted in the past several months that he will be making cameo appearance in the sitcom's last ever episode.

"I would definitely do it, yeah, yeah," he told Extra last October. "If they'll still have me, I will be there," he said about starring in the show's last season. "Yeah, I owe it some measure of closure. I owe it to the fans. I just think it makes sense."

However, since Sheen never did appear in season 12's finale, on Friday Chuck Lorre took to his website to explain why.

"I know a lot of you might be disappointed that you didn't get to see Charlie Sheen in tonight's finale," he wrote. "For the record, he was offered a role. Our idea was to have him walk up to the front door in the last scene, ring the doorbell, then turn, look directly into the camera and go off on a maniacal rant about the dangers of drug abuse. He would then explain that these dangers only applied to average people. That he was far from average. He was a ninja warrior from Mars. He was invincible."

Lorre added, "And then we would drop a piano on him. We thought it was funny. He didn't."

The show's creator/producer went on to reveal that Sheen had his own idea for his cameo, which was very different to their original plan.

"Instead, he wanted us to write a heart-warming scene that would set up his return to primetime TV in a new sitcom called 'The Harpers' starring him and Jon Cryer. We thought that was funny too," Lorre explained.
