A sock puppet is a puppet made from a sock or similar garment. The puppeteer wears the sock on a hand and lower arm as if it were a glove, with the puppet's mouth being formed by the region between the sock's heel and toe, and the puppeteer's thumb acting as the jaw. The arrangement of the fingers forms the shape of a mouth, which is sometimes padded with a hard piece of felt, often with a tongue glued inside.
The sock is stretched out fully so that it is long enough to cover the puppeteer's wrist and part of the arm. Often, the puppeteer hides behind a stand and raise the hand above it so that only the puppet is visible. Sock puppeteers may also stand in full view along with their puppets and hold conversations with them using ventriloquism.
Sock puppets can be made from socks or stockings of any color. Any sock may be used to create a puppet, but socks that are too tattered may fall apart during a performance, so they are usually bought new. Various additions can be glued on in order to give the sock a personality. Streamers and felt strings are usually glued on for hair. Buttons or googly eyes (obtained from craft or fabric stores) are used for the puppet's eyes. Clothes can be added, but this is not frequently seen.
Sock puppets are often used for the education and entertainment of children. They can be used in elaborate puppet shows or children's plays, much as marionettes would be. The process of making sock puppets is popularly taught as a creative activity in elementary schools. Many schools teach children to make sock puppets, which the students use to stage a play or musical.
Sock puppets appear in children's television series where they can be used alone on the puppeteer's hand, without a complex stage or show. Two orange sock puppets named Fu and Fara are used in teaching German children how to read. In the United States, sock puppeteer Shari Lewis was well known for her television show Lamb Chop's Play-Along featuring the sock puppets Lamb Chop, Charlie Horse, and Hush Puppy.
Sock puppets have also been used in television programming aimed at adults. The 1990s saw the introduction of the Ed the Sock character on the Much Music video network, and the Sifl and Olly show on the MTV music network. Both of these were aimed at teenagers and young adults. Sock puppets have also appeared in advertising geared towards adults. During the late 1990s, the ecommerce company Pets.com used a "spokespuppet" in its advertising to much critical acclaim.
