That reminded me of a story an old friend of mine told me, when he was an apprentice he used to have marmite on toast for breakfast in work everyday but somebody else was helping themselves to his marmite and when complained they all took the piss out of him, so he got pissed off one day and picked up all the dead flies he could find in the cabin and mushed them up in his jar of marmite the marmite was getting used and he kept up the moaning about it so whoever it was would still think it was funny and would carry on using it
