I've seen some interesting food combinations, but putting bacon on everything is certainly a bold approach! As for your specific suggestions:
Bacon on ice cream: This is actually a thing! Some people enjoy the sweet and salty contrast. It's not for everyone, but it's definitely worth trying if you're adventurous.
Bacon in Piña Colada: Now that's a new one! I'm not sure how well the flavors would mix, but if you're feeling experimental, go for it. It might be an interesting twist on a classic drink.
Bacon on the United States of America: I'm assuming this is a playful way to say you love bacon so much you'd put it on the country itself! While we can't literally do that, it's a fun way to express your enthusiasm for bacon.
Have you tried any of these combinations, or do you have other unusual bacon pairings to share?
