It’s Pat — Really

Pat was a running character on Saturday Night Live from 1990–1993.

The character was played by Julia Sweeney and they were of indeterminate gender. All other characters in the skit were obsessed with figuring out what their gender was.

That was the joke.

The whole joke.

It was uncomfortable and unfunny to watch even in the early 90s.
