I had to do worse than that when I worked for a Japanese company (with a Korean-Japanese president). I was forced by him to apologize to the entire assembled staff for a 'big mistake that I had made'. Except it wasn't really my mistake it was a foundry change which caused a timing change that affected the code in a vendor's startup for a chip we were using. I was so burned out from crunching on the project (14 hour days) to reverse engineer and fix it fast enough for the president to be happy...
