who is the father of judiths baby girl?

I think that there should be an episode where Judith, Alan, and Herb go on the Maury show

Im really sure that its Alan

No one can know the answer for sure because after alan had sex with judith herb did it the very Weiter Tag so know one can really decide!!

Alan Harper

its herb

It is very "unlikely" that Alan is the father of Herb and Judith's baby because he mentioned that he got a vasectomy (after Jake was born).
Here's a quote:
When I was married to judith it was my choice to get a vasectomy, new kitchen, and a labradoodle with a diarrhea.

Alan
