The crossing of a monkey and penguin as designed in the comics strip created by two geniuses in Washington Township, Michigan. Not to be confused with a mongoose, because whoever made that up is not paying attention obviously.
Also an aol screen name.
Matt Smith's Screen name is Monguin69 for aol and yahoo.
