I had three friends when I lived in the village I came from (I had more, but these three are the ones to do woth my bet).
They were son and nephews of the baker in our street, and we once made a bet I could eat a whole chocolate pie, it was called 'Herrentorte' (~Gentlemens's Pie) was about half as big as an original cream pie (Ha ha, not what we call that way, dudes ^^ ) and heavy on chocolate, nuts, and Marzipan. Price: 20 Deutschmarks
I made it about 2 thirds through, then had to give up.
It was worth it - but I learned all you can eat or food contest are not for me
