Pearly gates

Pearly gates is an informal name for the gateway to Heaven according to some Christian denominations.

"[1] The image of the gates in popular culture is a set of large gold, white, or wrought-iron gates in the clouds, guarded by Saint Peter (the keeper of the "keys to the kingdom").

Those not fit to enter heaven are denied entrance at the gates, and descend into Hell.

[2] In some versions of this imagery, Peter looks up the deceased's name in a book, before opening the gate.

The pearly gates provide the background for a joke cycle: "the premise of these jokes is that admission is not automatic but that the criteria for admission are somewhat arbitrary.
