What shoddy programming have you encountered?
I'm thinking that short descriptions are enough. Just the story, not the actual source.
For example...
A bunch of 'consulting grads' were implementing a system for a major retailer. Their 'tried and tested best practice' UNIX shell routines would log entries to a database table which had a primary key of type "date" (Oracle) - resolution to the second.
On the first occasion that multiple events occurred in rapid succession, the logging routine returned an error. This led to a call to the logging routine to log the error, which failed, which caused another call and so on.
They were fairly unhappy about being laughed at.
