Why Jon Cryer knew he had to put Charlie Sheen in his memoir

Jon Cryer worked pretty closely with fellow actor Charlie Sheen during their years together on "Two and a Half Men."

So, when it came time for him to write his memoir, titled "So That Happened," Jon knew he had to include Charlie's infamous downward spiral.

And he told Seth Meyers Tuesday night he didn't feel bad about it at all.

"It was a huge part of my life. It was fascinating to be in the middle of that hurricane, because it blew up so huge, and it was crazy. It was crazy every day, living that," said Jon Cryer on "Late Night."

Of course, Jon is talking about the year 2011, when Charlie began a string of very bizarre public behaviors that ended up getting him fired from "Men."

"I am on a drug. It's called Charlie Sheen! It's not available because if you try it once, you will die. Your face will melt off, and your children will weep over your exploded body."

Jon says he's rarely spoken to Charlie since that all went down. But he told The Huffington Post he hasn't given up hope on reconnecting with him one day.

"There was a guy I knew and worked with for several years and had a great time working with, and then he decided he didn't want to be sober anymore. I'm hoping there's a day that he decides that that's important to him again. And I'll be his friend when that day comes."(Video via The Huffington Post)
