Ho Chi Sock is Jack Howitzer's sock puppet, although Jack is convinced he isn't one and has a life of its own. He is based on Ho Chi, the sidekick of Howitzer's character Tim in the Evacuator Trilogy. Ho Chi is based on 20th century Communist leader Ho Chi Minh. Jack "met" Ho Chi Sock in the laundry room of Bolingbroke Penitentiary whilst incarcerated and he talks to him when times are tough. Sock "speaks" with stereotypical East Asian accent, his appearance is similar to that of a Vietnamese soldier during the Vietnam War; wearing a conical hat, green jacket, red neckerchief and holding a model SKS.
Sock appears in the TV series Jack Howitzer, he is used as Jack's Lifeinvader profile photo and has a blog post on Jack's website. He types with his mouth and his English isn't that good - he is prone to typos and his spelling is similar to that of a stereotypical East Asian; swapping Rs and Ls with each other and omitting short words. He has a grudge with Rufus Bellows, who wants Jack to get rid of the puppet.
