The first time I went there, my co-worker and I just started blurting out answers after some guy (Perry?) asked a question out loud. I didn't realize that there was a proper way of answering the question and we almost got kicked out. Needless to say, the guy withdrew the offer for a free sandwhich and said there would be no more questions for the day due to the two idiots in the back. We got nasty looks the whole time we were there.
