Silly Math Jokes, at your request

You know you had too much linear algebra when you look at a row of creamer pitchers at Willie's: skim, whole, low-fat, 2% milk, 1% milk, cream, buttermilk, half-and-half, soy, and think, "why so many? don't soy, skim, and cream form a basis?" Q: Why do truncated Maclaurian series fit the original function so well?

A: Because they are "Taylor" made! In a dark alley, a function and a differential operator met. The differential operator said, "Get out of my way or I will differentiate you till you are zero!" The function said, "Go ahead make my day; I am e^x ," and walked away with a smirk.

The function met another differential operator, and the latter said, "Get out of my way or I will differentiate you till you are zero!" The function said, "Oh yeah; I am e^x ," to which the operator replied, "Hasta la vista, baby, I am d/dy !"
