Mixed Hold 'Em final table - FBT shenanigans?

[MrBananagrabber]

From Steve Billirakis' Wikipedia page:

"During the final table, Mueller teased Billirakis about his youth, and made a feint of putting chips into the pot to attempt to get a read on whether Billirakis wanted him to call. (This is considered a breach of etiquette but not a violation of the rules.)"

Does anyone know if FBT was genuinely playing around, or really angle shooting? Did I miss any threads about this?
