November 13 is Felix Unger Day.

It’s observed on this date because Felix’s wife threw him out on November 13, according to the opening credits to the TV show.

On November 13, Felix Unger was asked to remove himself from his place of residence. That request came from his wife.

Deep down, he knew she was right. But he also knew that some day he would return to her.

With nowhere else to go, he appeared at the home of his friend Oscar Madison. Several years earlier, Madison’s wife had thrown him out, requesting that he never return.

Can two divorced men share an apartment without driving each other crazy?

There’s a Facebook page dedicated to making Felix Unger Day a national holiday.

One way to celebrate Felix Unger Day would be to honk along with this collection of clips of Felix clearing his sinuses (includes both Jack Lemmon and Tony Randall versions of the character).
