Someone did sometimes similar to my group for other reasons*. He insisted, during prep, that he was the "group leader" (no such thing) and that he was to be the point for all questions. So, I stepped behind him when question time started, and let it happen. This lass kept firing off question after question. It took everything out of me not to laugh after the third round of questions, but I'm sure I let a few smirks loose (I'm no god, after all). After 7 or 8 miltipart questions, he gave up and stomped off, all red in the face. After he was gone, I waiting a few seconds to make sure he wouldn't return, then asked if there were any other questions. I made eye contact with her, she smiled and said, "nope. I'm good". She was kind and in topic the whole time, so prof didn't intervene. Best econ class I ever took, at uni or elsewhere.

*The lad I was presenting with was a notorious wanker. There were some rumors, too, but I won't get into that.
