one of the funniest moments of the series for me, the timing was impeccable
hes stood there for days trying to hold up his money bag to win prize money for the fund....to ease the boredom he plays the yes no game with sam, ye immediately says yes, and puts his hands to his head in despair, when BANG down goes the money and poor jack falls flat on his little pie face

it was classic dipstick comedy in the great traditions of clowns cocking everything up , whether it be basil fawlty , frank spencer, jim carrey or ricky gervais playing a schlep, or way back to laurel and hardy
it all just makes me like him more, hes a natural character and very few others could supply such a moment of hapless comedy
