October Fool's Day

The first day of October (October 1st) which is similar to the first day of April (see April Fool's Day) where lies are told under the excuse of an observed holiday. First observed by Nintendo after their absolute joke of a Super Smash Bros. Ultimate reveal on October 1st, 2020.

Person 1: Hey, what prank did you pull for October Fool's Day?
Person 2: I announced a bad character for Smash!
Person 1: Wow, so original...
