Have you ever seen the movie you and me and everyone we know? This makes me think of the quote "You poop into my butt hole and I poop into your butt hole...back and forth...forever." I know it sounds strange, but if you've seen the movie you'll get it :) If not, it's definitely worth a watch and I feel like you would like it.
thanks guys - I love taking photos of them - the stripes are mesmerising
