"X need not apply" is a well-known trope that has historically been used in a discriminatory sense, e.g., "Irish need not apply."

"Humans not invited," isn't super derivative of either...

It's still an excellent video that almost everyone should watch. It's dated, a little, but I am pretty sure it is still going to prove all to true.
