As the series-long Janet is talking to another Janet from The Good Place, the latter is asked for various random things from a resident; starting and ending with a Coke. The Good Place Janet is already holding the first Coke in her hands before being asked for it. It can be clearly seen from 10:57 to 11:03.
When they get to the Good Place, Janet says that she had never been there. Technically, the gang had been to the Good Place in season three, but never left the building they were in.
Tahani claims her godfather is the famous clock "Big Ben." While the clock's largest bell's name, Big Ben, is often incorrectly used to refer to the entire clock, Tahani should be aware that the clock itself is actually "The Great Clock of Westminster."
