Great thread on Reddit on getting challenged on something and then turning the tables. Here's one example:

Oh boy do I have a story for you.
So when I was younger about 15 I think I moved to a new school because I had changed houses. While growing up since I could understand board games I played chess. Chess club chess tournaments chess everything. You name it I know it about chess. I had gotten so professional I was almost a grandmaster.
Anyways so I go to this new school and I see there's a chess club. I show up to the chess club on its first day and ask to join. So they let me in because they let everyone in its a school club. Apparently that school played very competitively. So first day of club its announced there's going to be a tournament next week. So all the other kids are trying to help me out and show me moves they think are good. The teacher running the club was even like no you should be doing this even though he was wrong. So the day of the tournament comes around. I'm playing my way up the ranks until I'm against the last guy. I beat the best player and everyone is pretty impressed so I ask the teacher if he wants to play a game. Of course the teacher being the teacher is like bah I'll wipe the floor with you I made it to regionals last year I'll let you know (I won them) so we play and I wipe the floor with him. We play a second because he said he was going easy and there's one point where he does a move I do a counter move and he goes that's wrong do this instead to which I go no it's right. He goes I know the guy who placed second in regionals and then I look at the teacher make my next move which puts him in checkmate and go yeah that's the guy I beat.
