Hell yea the poop knife. His family had one because their shits would block toilets. He thought it was a normal thing to require and have a poop knife but after going to a friend's house and asking for it, he discovered that it was indeed (Samuel L. Jackson voice) not a normal thing to possess.
Disagree- as someone coming from a family with similar abilities, this is more related to volume and personal flexibility. Just because it's extra large doesn't mean you have been constipated or not eating enough fibre, sheesh.
