Kelopuro Survives Amind Brunson Pen Mystery

On the first hand of the day, a short-stacked Sami Kelopuro pushed all in from the button after the action had folded around to him. Perhaps to the Finn's relief, the blinds folded.

Doyle Bunson is on this table - and was, in fact, the big blind in that hand. Brunson appears to have some curious wet patches down his front whilst a lady is rubbing a white tipped pen onto his shirt. Spilt coffee, I imagine, but what on earth is the pen? Answers on a postcard please...
