After Samir's first successful entertaining set, it can be seen "The Dummy" from the original The Twilight Zone (1959) episode The Dummy (1962) lying at the dressing-room. This ventriloquist dummy can be seen sitting on a table in the corner. That dummy, as Kumail Nanjiani confirmed to Vanity Fair, is not just any prop, but a puppet from the original Twilight Zone-a piece of set decoration worth millions of dollars, and owned by none other than David Copperfield. The magician agreed to lend it to the show on one condition: the new series had to reference its benefactor in some way.
When Samir browses his phone contacts, one of the names he sees is "Denton, Al", a reference to Mr. Denton on Doomsday (1959).
An "apostrophe," in addition to being a punctuation mark, is also a speech directed to someone who is dead or not present.
(Around 24 minutes) Samir is looking at someone called Henry Corwin on his laptop. This is the name of the character who becomes Santa Claus in the original series episode The Night Of The Meek.
First Twilight Zone episode ever to have the "F" word.
