"Surprise is the essence of humor, and nothing is more surprising than truth." – Bill Watterson (author of Calvin & Hobbes)
The now-famous Gorilla Test is a comedic, amusing, funny, laughable, little experience while you're a spectator, watching it from a distance. It's an altogether different experience when the beast shows up in your life. You'll find that pointing at the invisible gorilla is not a fun thing to do when people who lack a sense of humor are involved. If you can't laugh at yourself, then you're not much of a person. Life rule: don't mingle with humorless people.
