Three questions:
Why do some visitors to Jerry's building buzz his intercom,
and other times, just arrive at his apt. door with no prior
notice? Even Elaine and George occasionally need to be buzzed
in. Related issue: I know this is necessary for the Kramer
entrances, but would any New Yorker leave his apt. door
unlocked all day? Has any episode ever shown Jerry's mountain bike taken off
it's ceiling hooks? Why would Jerry keep 12 or 15 apparently opened breakfast
cereal boxes in his kitchen? Half of them must go stale.
