Laws of Mathematics that Govern Institutional Research:
Grabel’s Law: 2 is not equal to 3. Not even for very large values of 2. (The only exception is when your provost intervenes.) 

The Fundamental Theorem of Analysis: Any theorem of analysis can be proven on an arbitrarily small piece of paper provided the author is sufficiently vague.

The Golden Rule of Teaching Mathematics: You must tell the truth, and nothing but the truth, but not the whole truth. (Also true of wedding toasts and eulogies.) 

The Golden Rule of Deriving: Never trust any result that was proved after 11 pm.
