Do you report brain dumpers?

I have a coworker that just passed his last exam in the MCSE track and finally got his MCSE.
Was happy for him but wanted to know how he got it so darn fast. We started studing about the same time and I have not even gotten my MCSA yet let alone an MCSE.
So I asked how he did it and he told me he used .... well lets just say it is a known brain ****.
I was kinda shocked that he would use those!
What to do?
I mean do I just pretend I never heard him say that - what would you guys do?

Not to mention the whole tattle-tale part. You don't want to narc on your co-worker for something like that; especially if they don't know about brain ****. As I said, it will come out sooner or later when/if he doesn't know what to do in a tight situation. I'm not trying to defend him or anyone else that uses a brain **** but there are too many "if's" and "he-said, she saids" and you don't want to get into the middle of something like that. Office politics and enemies ftl!
MCTs are a different story. Report them.
Or keep asking them questions about stuff you've learned with proper study and ask them do they know much about it. Just to twist the knife a little on them. Accept any lame explainations and the next day say "I looked into it last night and you were wrong when you told me that yesterday"
Just keep doing that till they feel stupid...
