United Kingdom, March 18 -- Brian Austin Green was fired from a sitcom because he didn't "understand the timing" of comedy.

The 52-year-old actor has recalled being fired from his role on My Two Dads, the American TV sitcom, before landing the part of David Silver on Beverly Hills, 90210 in 1990.

During an appearance on Pod Meets World, Brian shared: "I was on one episode of My Two Dads and it was the only time that I was ever fired.

"We had been rehearsing, and then we did a run-through, and I had a scene sitting at a table with Staci Keanan, who was on that show, and there was somebody else and I was really new to sitcoms and I just didn't completely understand the timing of it and . they were like, 'We're going to have to recast.'"...
