Season 5, Episode 2 of 30 Rock.

Liz claims to love having had an ‘old dad’ because she could get away with anything. Flashback to her in front of a liquor cabinet saying, ‘this is just what I need…

…to store my rock collection!’

Two minutes later in the episode, we find Jack lying on Liz’s couch in her office, present day…

…clearly holding the bottle Liz stored her rock collection in from when she was a teenager.

This show is pure fucking genius and I never want it to end.
