What is absolutely hilarious as long as it's not happening to you?

Chasing after a paper blowing on the ground
When kids mistakingly embrace a stranger thinking it's their parent. As a child this is terrifying, as an adult it's adorable and hilarious.
People who take like a whole 10 seconds to actually fall over. Drunk or on icy surfaces. They try so hard to right themselves but always come crashing down.
watching someone almost trip then do the half jog to walk it off casually
Failing at parallel parking with a crowd of onloookers.
Waving back at someone whose wave wasn't intended for you
Bursting out in laughter while drinking something. Or alternatively, getting wet from a person bursting out laughing while drinking.
Accidentally saying "I love you" when leaving a coworker due to habit
Calling the judge “Your majesty.”
Someone getting pestered by a wasp to the extent that they run away, flapping their arms at the tiny yellow and black bringer of doom.
Throwing something then having it bounce and hit you in the head
Looking somewhere else and then walking into a pole.
Watching someone try to teach a 100% incompetent coworker a new skill.
When somebody answers a question so wrong that you start to wonder if they're even in that class or they sat down in the wrong lecture.
