I Col! I Fol'!
In addition, all of Joao Barbosa's chips were across the line, suggesting that he was all in.
Furthermore, Barbosa's hand -- -- was face-up, and his opponent Andrea Sighinolfi's hand -- -- was also face-up, rather suggesting that Sighinolfi had called Barbosa all in.
The dealer began to deal a turn... when Sighinolfi removed his current lollipop from his mouth (he seems to have an endless supply) and piped up that what the dealer and some of the players had heard as "Call" was actually "Fold" and he was merely showing his cards before handing them back to the dealer. It seems that "call" and "fold" sound similar in an Italian accent. Much hilarity ensued.
