A self-deprecating joke lands once. Told every day, it starts sounding true to you too.

Jokes at your own expense buy a quick laugh and then quietly turn into a description. Say it often enough and two things happen: the people around you begin accepting the label, since you supplied it, and you start hearing it as a fact rather than a bit. The audience moves on and the sentence stays behind in your head.
Retire your main one for a week and see what you say instead. If you need a joke, aim it at the situation rather than at yourself.
Which joke about yourself have you told too many times?
Free, with nothing to buy inside it.
