Don't pay attention…
...to that man behind the curtain. 
Much of the power of Pig comes from user-defined functions (UDFs). 
In fact, as a user of much more powerful functional programming systems, I think Pig has remarkably few builtin functions (and I miss some of the builtins in FP)
For this lecture, I will concentrate on the power of Pig itself, 
So I will start with data that has already been massaged by UDFs into an appropriate form.
