The Cannonball Challenge consists of eating nothing but cheese for a week straight whilst forcing oneself to not poop. On the last day, one must take laxatives equivalent to 10x the regular dosage.
Later that night, one will poop and release a cannonball of shit into the toilet and post it online, tagging 10 friends and challenging them to attempt The Cannonball Challenge.
My friend and I attempted The Cannonball Challenge. Ever since, I’ve had consistent bloody stools. On the bright side, food goes right through me now!
