lol chill, I think the plagiarism thing was more a joke than a harsh accusation!
Speaking of which, 2 students on my course a couple of years ago decided to hand in the exact same written paper for an assignment. Not having dealt with this before on the course, the course tutor decided to call them in to the office to talk about it. Obviously they were expecting some made up story about how they had no idea they were the same, or they didn't know what they were talking about...
No, they both just said, "Oh... well we both worked on it and contributed equally. Weren't we allowed to work as a group?"
