If I read the schedule correctly (never more than a 50% probability), the episodes of The Daily Show with Jon Stewart that run during the day on Monday are both last week's outing with guest Tracey Ullman. The Daily Show airs three times a day on Comedy Central. The last of these (at 7:30 or 10:30 PM depending on your time zone) is that day's new episode. The episodes that air earlier in the day are reruns, usually of the previous installment.
The reason I mention this is that I found Ms. Ullman to be fall-down funny in this appearance. Can't recall the last time I laughed so much at a "chat spot" on any talk show. You also get to see her underwear but even without that, it would be worth catching. If and when they put a clip up on the Comedy Central website, I'll post a link to it. In the meantime, if you watch, TiVo or tape either of the during-the-day broadcasts on Monday, you should get it.
