Jon Cryer

Jon Cryer is poking fun at his former castmate Charlie Sheen's comments that he's a troll.

In a monologue on Thursday night's Conan O'Brien, Cryer said that while Sheen's words were painful, the truth is, he is a troll.

"You have no idea how much time and money I've spent on electrolysis and hair dye and reconstructive surgery so that I can look like this instead of this," he said, showing a picture of him as a troll with bright pink hair.

Cryer also addressed the common misconceptions about this creature.

"That we drink the morning dew from buttercups — so not true. We're the guys who dangle from little girls backpacks and sit on the back of pencils!" he said with a very "serious" tone.

Also mocking the recent anti-bullying campaigns in Hollywood, Cryer added, "To all you other trolls still living under the bridge, especially you younger trolls, I'm here to tell you it gets better. Not gay better, but sort of better."
