I actually did see her on Broadway in The Tale of the Allergist's Wife (alongside Michele Lee and Tony Roberts), but unfortunately did not get to hang around the stage door to find out for myself (we didn't have time). I heard the rumors after the fact, though.
There's also a Simpsons...
What are the running times of the episodes?
EDIT: I checked Sitcoms Online's review, and they all appear to be the same lengths as they were on iTunes, which is good
