One of my math professor (Canadian) once told us a story (~10 years ago) that the US border control asked him to "state and prove Rolle's theorem" after he had told them he was traveling to a math conference. Apparently he answered "it's something to do with the mean value theorem, right?" and that was good enough.

Thanks for the answer, I deleted my original question shortly after posting because I thought it was abit disrespectful.

For those who are curious, the question was: is "for Hackers" a new way of saying for those who don't feel like actually studying the math, going through the proofs and working through the problem sets?
