Visible crew/equipment: At the very beginning of the scene where Alvy and Annie are arguing over Annie's adult education teacher, David, and Annie is getting into the cab, a film crew member is visible up the sidewalk, just above the roof of the cab. As the scene starts, he drops his arm as a timing signal to the old woman carrying a grocery bag to begin her walk into the scene, where, seconds later, Alvy turns to ask her a question. (00:52:25)
Alvy Singer: Sun is bad for you. Everything our parents said was good is bad. Sun, milk, red meat... college.
Question: I couldn't understand the joke in the beginning ("In such small portions"). Can someone explain it to me, please.
