Sebok is quoted as having received advice from Barry G. during the final table of the WCOOP.
Too lazy to look for the quote, but I believe it was on the Pokerstars Blog!!!
Edit: I found it:
When I reached 90,000 in chips my dad came in and decided to sit down and watch me play. This was about six hours into the tournament. Now I can't deny that it certainly isn't bad to be able to have Barry Greenstein come in and take a seat next you, counseling you through the later stages of such a big tournament. Let me assuage your fears though, as he did not actually play for me, as you may think. We would occasionally talk through hands when things got a little dicey though.
At any rate, our partnership became one with the feel of student driver/instructor. Every time I was driving fine and parallel parking like a pro, we would have a conversation like this:
"Joey, you really need to raise in here again."
"But Bear, I have a 9-4 off. Come on, you are being ridiculous."
"I'm telling you, these guys are so scared of you that you should be raising every hand. If they refuse to stop you, then you shouldn't stop yourself."
