First off, I can't spell 'bouquet' to save my life, so if I misspell it anywhere here, please don't hold that against me and not marry me in the future (k future wife, she knows who she is):
Now that's out of the way, let's get into how either great or ridiculous this idea is..because we all have said that "pizza is bae". And if you're going to float those words out there, then maybe actually mean it? By walking pizza down the aisle?
Now look, you aren't actually marrying a pizza, ladies, you get a pizza bouquet and the groom gets a pizza boutonniere, both of which I'm positive I'd eat before I ever said "I do!".
I'd marry pizza, I'd hug pizza, basically my future wife is probably going to be pizza
