Hey! Let's make Joe recurring on "Old Christine"

I'm still catching up on TV shows after my all-to-brief vacation. Monday night marked the welcome return of the very, very funny Julia Louis-Dreyfus sitcom "The New Adventures of Old Christine." I have loved this show since its premiere last year and it remains FUNNY.
The first show that aired on Monday was a repeat but I had never seen it before Old Christine's ex-hubby Richard (his new girlfriend is known as new Christine to avoid confusion) has a really hot brother named Joe who is played by Charles Esten. Joe is struggling with being gay but realizes, after kissing his former sister-in-law Christine, that he is indeed gay! He's not ready to come out to big bro but old Christine, always the blabber mouth, spills it. A series of lies and misunderstandings follow and it is all very funny. New Christine even blurts out that she was briefly a lesbian while in college.
TV Guide, in its weekly "Cheers and Jeers" column, gives a cheer to Esten "for his witty turn as Julia Louis-Dreyfus' ambiguously gay ex-brother-in-law." The magazine notes that Esten is an alum of "Whose Line is it Anyway?" and "is one of those rare actors who's equallyg funny AND handsome."
So here's my idea: why not have him show up on a regular basis to stir things up? Maybe he can hook up with Christine's brother who's not gay but sure seems like he should be!
