A great story from Reuters: How a student took on eminent economists on debt issue - and won. The student is Thomas Herndon, in the UMass grad program in economics. This thing is buried deep inside the report, but worth highlighting:
Herndon's paper began life as a replication exercise for a term paper in a graduate econometrics class.

In the comments section, we find a link to EuSpRIG, The European Spreadsheet Risks Interest Group -- with its own annual conference. Its website has a page devoted to spreadsheet horror stories. The RR paper hasn't made it to this page so far, though.
