The doctor is definitely in on the fresh February 10 episode of CBS’ The New Adventures of Old Christine called “A Family Unfair.”

Even cooler for fans of sketch comedy television is the fact that the physician is played by Saturday Night Live veteran Tim Meadows.

All four of CBS’ Monday-night sitcoms have new episodes scheduled for February 8.

How I Met Your Mother even features a couple of cool voice-only cameos from sports figures Jim Nantz and Phil Simms, both prominent members of CBS’ on-air sports departments.

Veteran television actor and The L Word alum Steven Eckholdt guest stars on “Crude and Uncalled For,” the fresh February 1 episode of CBS sitcom Two and a Half Men.

He plays Brad, Alan’s lawyer, whose help is desperately needed…

Unfortunately for viewers, there isn’t an actual ginormous female on the brand-new February 1 episode of Accidentally on Purpose called “Attack of the 50 Foot Woman.”

Instead we have the same old familiar Billie, who’s behaving extra manipulatively, but for a very good cause.

Aaah! A new month, a new episode of CBS’ hit sitcom The Big Bang Theory. Coming up on February 1 is the Sheldon-centric “The Einstein Approximation.”

And I bet Penny is going to be thrilled during the action, too.

New York Yankee Nick Swisher and CBS sportscaster Jim Nantz drop by How I Met Your Mother to play themselves during the brand-new February 1 episode “The Perfect Week.”

The title refers to lucky Barney, who’s having a fantabulous week thanks to his skills almost hooking up with seven women in seven days.

Television viewers who love The New Adventures of Old Christine are really going to love the brand-new January 20 episode “Truth or Dare,” which features returning guest stars Blair Underwood (In Treatment) and Eric McCormack (Will & Grace).

The actors play Christine’s ex-significant other Mr. Harris and her therapist and current significant other Max, respectively.

In addition to Neil Patrick Harris‘ directorial debut with the new January 18 episode of How I Met Your Mother, CBS’ remaining three Monday-night sitcoms will present new episodes, too.

And featured on Accidentally on Purpose and Two and a Half Men are guest stars Michael Rapaport (My Name is Earl) and Stacy Keach (Titus), respectively.

How I Met Your Mother fans are in for a real treat during the January 18 episode “Jenkins,” which happens to be directed by none other than series star Neil Patrick Harris, who’s making his directorial debut with the installment.

Also of note is guest star Amanda Peet (The X Files: I Want to Believe, Studio 60 on the Sunset Strip) as the title character Jenkins.

Wonder Years alumna Danica McKellar guest stars on the new year’s first fresh episode of The Big Bang Theory, January 11th’s “The Psychic Vortex.”

McKellar stops by to portray Abby, a potential romantic interest for adorable yet woman-shy Koothrappali. I hope he gets really lucky.
