Towel

A towel is a thick rectangular cloth that is used for the purpose of drying up liquids from a person or an object. It is also used for maintaining one's personal dignity when they are without clothes, as in the case of a Smurf character in the comic book version of "The Smurfs And The Howlibird" when the creature destroyed the clothes he had on the line.
