Twitter user Ailsa Burn-Murdoch tweeted the below picture today, after finding a dumpster overflowing with pizza dough during her morning commute in Edinburgh. It appears as though a Papa John’s employee forgot that dough has a tendency to expand when left out. Some pizza expert they are.

Papa John’s is furiously investigating the cause of the most important mystery of our time. We’ll place our bets on “lazy employee.”
