What’s the funniest sign and why is it Sagittarius?

Ive always known that there was something about them when the funniest people I know all have Sagittarius placements but it was really confirmed when I got back into kpop.. watching certain idols actually had me laughing my ass off n sure enough, they all have at least one Sagittarius placement in their big 6, mostly sun and mercury ?? I actually need an explanation behind why Sagittarius placements are so funny 😭😭 honorable mentions to aries moon/mercury, virgo mercury, capricorn mercury, & gemini moon tho !
