Anyone ever tried the Shakespearean Insulter (http://www.pangloss.com/seidel/Shaker/index.html?)? It will put together words from all of Shakespeares works to form a new insult every time you press the button. :D

Examples:

Thou errant spur-galled malt-worm!
[Thou] small grey coated gnat.
Thou churlish earth-vexing horn-beast!

Enjoy!

This is good also!
