Our shop language is Perl, but we present database backed web apps to other departments and to the customers of our cable/isp. This means we have to deal with SQL, HTML, and recently a lot of JavaScript (though one of my colleagues likes that, so he does most of it). We also deal with hardware on occasion (like the kind the routes phone calls the old fashioned way). These devices tend to speak C.

So that leaves us about 90-95% perl with a few odd bits thrown in.
