Jim Parsons thinks "The Big Bang Theory" was right to end because he'd done everything he could on the show.
The 46-year-old actor had played Sheldon Cooper for 12 years and though fans were sat when the show recently came to an end, he insisted it was the right time to step away because he'd done everything he could with his character.
He said: "I played the s**t out of that character, and some people could have done it longer probably -- I don't mean our show, but this relationship with the character.
"But I feel like we really wrung that material for what it was."
And Jim admitted it was very unusual for someone in a "creative profession" to stay in the same job for such a long time.
