Hilarious 21st Birthday Puns That Deserve a Standing Cheers

On my own 21st birthday, I wore a glitter crown, toasted with champagne, and told a bartender that pineapple juice “totally counts as hydration.” It did not. Somewhere between bad dance moves and questionable snack choices.

I realized 21st birthday puns are the real party starters. So here is a list that is as fizzy as your first legal drink; no fake ID required.
