Yeah I regularly see columns named [SomethingDescrption] in real life and posted here in queries too, where someone didn't spell it right the first time and then it hangs around like that forever. I also saw a column named InvoiceDetails.[InvoiceDetailslId]. See that l? Me neither, for a long time.

Worst of all, were dozens of stored procedures that used dbmail and the word "udpate". They must have been copied pasted or done by a dyslexic but my email inbox was filled with "udpate successful" and "udpate failed" emails for a year before I was confident enough to go through and fix them all.
