When we spot something extraordinary stupid in a student's exam answer, we call it "a humor of students' exercise books" and we publish it (of course without student's name).
The thing I found in the answer to an exam question to the course on XML techniques, made me laughing for an hour or so.
The questions was "What is RDF? Describe its current use by publishing media".
The answer was: "The RDF is something used by media to adjust car receiver frequency to the radio station and display it on the radio display"
Wow - it is really good answer. Particularly as for XML technologies student :-)
