I saw a video of some daring men celebrating in their unique way. I DO NOT recommend this method, someone can be injured but it was hilarious to watch it happen:
Light a string of firecrackers (Black Cat etc.), while they are lit put them in the toilet bowl, sit on the toilet wearing your undies, wave the Stars and Stripes while singing "America the Beautiful" and wait for the "explosive" conclusion LOL

Happy 4th of july!
