Star-Crossed Lovers and Other Strangers - S1-E16
Visible crew/equipment: When Rory asks Lorelai to call Emily to get her out of Friday night dinner so she can celebrate her and Dean's 3-month anniversary, a boom mic drops into the shot as Lorelai stands to get the phone. (00:07:05)
...And Four Stolen Hooves - S1-E1
Visible crew/equipment: When the jockey falls from the horse, there is a 2nd quick shot of the same scene, to extend it a few seconds. In the first part, the horse is running free; in the 2nd, we can see the bridle that's leading the horse forward. (00:36:20)
