When my fiance's uncle was married in the early 90s he ad-libbed a line at the end of his vows and said "and I vow to protect you from ninjas and pirates." Ever since then everyone in their family says this line as part of the vows. To them it's a closely held tradition that has even extended to family friends. I have been to 3 weddings with my fiance and every single one of them the groom said the line. On one occasion it got a really big laugh, on the other two it seemed to just like confuse people and the people from my fiance's family barely snickered.

I understand it's a tradition but I don't want to do it. I am not a funny person and the thought of even being up there makes me nervous, much less drawing attention to myself by making a joke.

My fiance says that "you have to do this" and that she's been looking forward to this part of her wedding since she was a kid. It's become a major issue for us and we are upset at each other all the time over this.

Are there any solutions to this that I'm not thinking of?

Thank you for offering your opinion.

Title. There's no doubt a lot of accounts that completely mess up our timelines of history in our heads.

I'm not talking about "Egyptians are old" type of posts I sometimes see, I mean "gunpowder was invented before composite bows" (I have no idea, that's why I'm here) or something like that.

Edit: "What other some others" lmao okay me
