Two and a Half Men

Show Co-creator Chuck Lorre wrote the show's theme song.

When the show won the People's Choice Award in 2003, Angus T. Jones (Jake) accepted it on behalf of the cast and crew.

Legendary actress Blythe Danner was the original choice for Charlie and Alan's mother, and even started rehearsing with the cast. But she reluctantly had to drop out due to other conflicts.

At a convention of television critics during the summer of 2005, Chuck Lorre confirmed that the show's opening tune is performed by studio musicians and not by actors Charlie Sheen, Jon Cryer and Angus T. Jones (who merely lip-sync the lyrics).

The fridge in the set kitchen is actually functioning, which is unusual for television shows.

Charlie Sheen, Jon Cryer, and Holland Taylor (Evelyn Harper) all share the distinction of being in a John Hughes film. Ferris Bueller's Day Off (1986) for Sheen, Pretty in Pink (1986) for Cryer, and She's Having a Baby (1988) for Taylor.

Each episode derives its title from a line in the working script.

Alan's alimony is $3,875 dollars a month.

Sarcastic housekeeper Berta was originally supposed to be a recurring character, but actress Conchata Ferrell proved to be such a hit with the audience, that she became a regular cast member at the start of season two.

It's never mentioned as to what Alan’s ex wife Judith does for a living. Alan is a chiropractor, Charlie is a jingle writer, Evelyn sells real estate, Berta is a housekeeper, Kandi is an actress, and Rose sits on the board of directors at her father's bank.
