When Maria is eating breakfast with Brody, from the back we see her cutting pancakes with a fork, but from the front she has both hands under the table.
When Rath is talking to Liz and Liz walks away you can see Rath move to grab her, but when the angle changes he's still walking, then moves to grab her again.
Brody at the alien museum asks Maria, "So what do you think of our new president?" The episode aired November 20, 2000 but when they were filming earlier, they would have assumed that by the time the show aired, the USA would have a new president elect. In fact, due to the Florida recount in 2000, the USA did not have a new president elect until December, after this episode aired.
