I'm sure we (I'm referring to web developers) have at one time or another used a web scripting language like php, perl, python, or asp.
But, we know you can also write cgi applications in languages like C.
So, has anyone used an unusual language for writting CGI applications? By unusual, I mean a language that is not generally known for writing CGI apps with. Please make sure your answers are about languages you have actually used to write CGI apps - although bizzare languages may be mentioned for humorous effect.
Edit - to make this more educational, please include links to the languages you reference. - unless it's a common language, like pascal.
