thesaurus 

1. A major source of humour for anyone who has really nothing at all to do.
2. A dinosaur? Possibly.
3. A book which contains synonyms. Ironically, the word "thesaurus" has no synonyms.

1. Hey, apparently, "dice" is a synonym for "frangepanni" and "frangepanni" is a synonym of "bad spelling"!
2. (see the entry for "Thesaurus" below...)
3. z0mg, ROFLMFAO!!!!
