Plop...plop...plop...
The foreigner looks around in the semi-darkness, unable to discern anything that might encompass such a sound. The thought of opening a champagne bottle on new year's eve slips briefly past his mind's eye before it makes place for the more interesting flickering of the big screen...

The Dutch moviegoing collective sees a mind plop, opening it to beerly influences of a good kind;
"Ah, Another enlightened foreigner."
