It says... "Fit / Remove worst point / i'm out of points / don't need a model anymore // add 1 feature / i'm out of features / add Y to the features // R² going up? / Yes / Lucky me! / No / R=1? / Yes / Found the 'real' model!" but that's only funny on the T-shirt.


Why it is funny: because it mimics some of the mistakes beginners (or bad statisticians, if such a thing exists) do when fitting a model. R² is not a good predictor on whether you're close to the real model or whether your model will perform well on new data. To try an awkward comparison, the R² is like the Donald Trump of goodness-of-fit indicators, and it will NOT make your model great again.


Nice to wear at a dance club, when you definitely want people to come very close to you, so they can read the whole thing.
