Pilot (aka Emotions in Motion) - S1-E1
Visible crew/equipment: It's morning at Jen's and Grams'. Jen is seated at the kitchen table downstage/far left. Grams is upstage/right at the stove scrambling eggs. Grams crosses downstage to put the eggs in front of Jen and the mic overhead upstage/right peeks out just a tiny bit. Grams crosses back to the stove. Suddenly the microphone - including the rod the mic is on - just drops down almost completely into the frame over Grams' head and is not pulled back up.
