Love the test!! Of course, hopefully some errant mistake never results in fucking "unprofessional" language making its way into production code. Personally, I find that sprinkling funny fucking shit in my tests is the best way to keep my interest. Plus, the test output is fun too; nothing beats an obscenely profane test suite.
