This episode has been my favorite since it first aired in 1999. "Will & Grace" had many, many funny episodes since this episode aired, but I don't think any episode has compared to this one. I believe "Will & Grace" is best whenever the four main characters are together in a scene, and they are for most of this episode. Well, the fact that Jack's mom is so naive that she never knew that Jack is gay is a little far-fetched, but the jokes that come out of that set-up are top-notch. This really was thirty minutes of continuous laughter.
Note: I can't believe they never brought back Veronica Cartwright to reprise the role of Jack's mother.
