Today I walked into Kieron's summer class to proctor some quizzes. Justin is the official TA and had some car trouble (oil change).
So, I went in and pulled Kieron's old trick of introducing yourself as someone else so they'll take the heat if something goes wrong! Normally if I introduce myself as someone else in the group (we're all interchangeable, really), then things go swimmingly.
Not so much this time. The students practically called the police on me.
