When I was teaching in Saarbrücken, I once took an English-German translation test when I was supposed to be proctoring the German-English test that was to take place after the E-G test. Since my colleagues were going to be doing the grading of the E-G test, I could not hand it in under my own name, so I wrote "Jonathan Schild" on the test (my middle name, and the German version of my last name).

My colleagues did not get the joke until I revealed my identity to them. I had gotten a B+.
