IDtenT problem

Joke among I.T. types, vehicle and appliance mechanics, who will write out "ID ten T problem". When substituting the number "10" for the text "ten", the word resembles "Idiot".

The person diagnosing will say "ID ten T problem" with a smile on their face, but they are calling you an idiot.

The tech form read "IDtenT problem: Power strip circuit breaker needed resetting. PC then powered on normally."
