Me at a previous workplace.

-This is a piece of shit, who is the code owner of this module.

• Ah, it’s me (“inheriting” code ownership when someone left was common)

• Who did this change

• Ah, it was me

• Surely I just made a minor change to this line here, who wrote the function.

• it was me, it was me all the way down

Fits the general theme of the thread as it was not giving any trouble for a year before being found.
