Turns out Two and a Half Men's Jon Cryer didn't know his costar Charlie Sheen as well as he thought.
Speaking to David Letterman in a Wednesday interview about Sheen's wild outbursts and antics, Cryer says he had no idea Sheen would spiral out of control so quickly.
"It's as much a mystery to me as to everyone, I think," Cryer told Letterman of the behavior of his colleague, who was fired from Men March 7, weeks after a two-day bender landed him in the hospital and caused his series to halt production.
During the show's forced hiatus, Cryer, 46, says he watched Sheen's manic media interviews and was just as puzzled as the rest of Men's fans.
"My favorite moment was I got a text from someone, saying, 'Charlie Sheen just called Thomas Jefferson a pussy.' I said, 'I think things are getting out of hand,'" he told Letterman. "We didn't see where it was going. This has never happened before. It wasn't like, back in 1963, oh everyone remembers when Fred McMurray went bats-it and started talking about free mason ninjas and stuff. It was crazy! And Vivian Vance started urinating on the set of 'Here's Lucy.' So nobody was prepared for this."
Feeling slighted after being dumped from the show, Sheen, 45, took aim at Cryer, his costar for the past nine seasons. "Jon has not called me," a fired-up Sheen told E! News in March. "He's a turncoat, a traitor, a troll. Clearly he's a troll."
However, Cryer -- who appears on the series as Alan Harper -- harbors no ill will.
"I love him, he's a great friend," Cryer said of his costar. "None of us wanted to continue with the show if we felt like it was hurting him, and there was a point at which, we felt like, there's no control over him."
With Ashton Kutcher now on board to fill Sheen's role once the series resumes production, Sheen continues to forge ahead with his $100 million lawsuit against Men creator Chuck Lorre. Demanding he be compensated for the eight cancelled episodes from the current season, Sheen is also suing on behalf of the sitcom's crew.
