I have the feeling that valkyrie will like this one:
When I planning my wedding, and COMPLETELY stressed out, my florist happened to mention a bride in Long Island (I don't know which part) who had warned her fiance NOT to shove the cake in her face. Well, you know men - tell them not to do something, and they consider it a dare.
Anyhow, the idiot groom shoved the cake in the bride's face, and she picked up the cake knife, stabbed and killed him!

So, I turned to my then-fiance and said, "And let that be a lesson to you!"
In our wedding pictures, in the photos of the cake cutting, you could see me with a death grip on one of the cake knives - because I meant business!!
I've also been at bouquet tosses where:
-women have fought so hard for the bouquet that they ended up rolling under the head table;
-women needed stitches from scratching each other on the bouquet;
-one man had a black eye from trying to catch the garter.
It's one tradition that I can do without!!
