What year did whoopee cushion come out?

There's no definitive "year" the whoopee cushion was invented! It's likely a gradual evolution:

* Early Forms: Rubber-based "fart" toys existed before the "whoopee cushion" name.

* 19th Century: Some argue the first recognizable version appeared in the 1800s.

* Early 20th Century: Popularized in the early 1900s with the rise of rubber manufacturing and novelty items.

So, while there's no exact date, the early 20th century is when the whoopee cushion as we know it became widely available.
