Here's a fun fact for you - the world's most expensive coffee is made from elephant poop! Yes, you read that right, it's called Kopi Luwak and it can cost up to $700 per pound. But, don't worry, it's still calorie-free, so you can indulge without feeling too guilty.
Another interesting fact is that the world's largest cup of coffee was over 3,700 gallons! Can you imagine drinking a cup of coffee that big? I think I'd be buzzing for days. And, the best part is, it was still black coffee, so it was calorie-free, but I'm sure the sugar and creamer they added to it weren't.
So, why is it fun to talk about coffee calories? Well, for one, it's a great way to impress your friends with your random knowledge. And, two, it's a good excuse to drink more black coffee and feel good about it. I mean, who doesn't love a guilt-free cup of coffee?
