What is the funniest joke in the series?

[Pink Cat]

Mario is a good humored fellow, make sense that there would be a lot of funny moments.
So, what would be your favorite joke in the entire Mario series, sub series included.

Personally, I always crack of Mario & Luigi "Italian" gibberish in the rpg series

the credits in Mario vs donkey kong.

It's not a joke but funny/cute~

Luigi's finest excuse of getting out of anything.

Hotel Mario had that one intentionally and unironically funny moment where Mario's response to seeing Peach disappear for no reason is to look at the camera and say "it's been one of those days."

The whole thing about Mario & Luigi are tired of Bowser kidnapping Peach every Tuesday

She should do that more often, honestly.

Oh gosh, there's just too many to choose from to pick just one! But one of the funniest overall has to be that one Bowser segment in Paper Mario: The Thousand-Year Door where he encounters Lord Crump at Twilight Town. Shots are fired, they call forth their respective troops, Crump throws the Super Bob-omb to no effect; only for Bowser to foolishly set it off with his fire breath and... We all know what happened next...!

That entire sequence was so unfunny it actually made me laugh.
