I had 6 colonoscopy in 2 years. I know the discomfort and pure humiliating ass-pain. You have to have some fun with it!!
Quietly eat a bowl of ramen noodles when you are about 2/3 of the way through the jug of colon cleanse. Then, when you poop out the ramen as still completely whole noodles, act like you are panicked and call the wife/kids/parents into the bathroom and show them, asking “are those worms?????”
Do a colon cleanse challenge with your spouse or friends. Most people don’t believe when you tell them you *s-word clear water.
Swallow a couple gummy worms or gummy bears whole. Wait for surprise.
Eat a bunch of jelly beans. Wait for surprise.
