The 11-year-old boy Bobby was able to fix the computer issue by clicking a few buttons. When asked what the problem was, Bobby replied it was an "ID ten T error". The man did not understand the error, so Bobby told him to write it down. When written as "I D 1 0 T", the man realized Bobby was joking and the error was actually "ID10T", meaning an idiot error caused by user incompetence.
