Get the Jack some noogmug. Jack mcann is commonly found around large masses of fresh water, such as the murry river, lake epolock, and other creek systems. Jack mcann has a very low vocabulary consisting of “what c u n t” “ehhh” and other annoying words or murmur's. As an introduced species if you ever see one of these disease ridden jacks crossing the street or stealing juice boxes from your house make sure to exterminate it with no mercy.

Get the Jackmug. Jack is the kindest person ever. He is always wanting to make other people happy and sometimes forgets that he needs to be happy in order to make others happy. He is truely the nicest, good looking, sweetest, encouraging, resilient, compassionate, empathetic guy you will ever meet. He is literally good at EVERYTHING, even tho he denies it, he really is the best thing that will ever happen to you. He is fantastic at musical things and extremely good at sports. You are soooo lucky to have someone like a jack in your life because he will make you smile, even if he’s giving the saddest news in the world. His smile lights up your world and his eyes are gorgeous, light blue in colour. Jacks are very rare and you need to show how much they mean to you a lot because they deserve to know how much they mean to you. They need to be appreciated.
