A function is a command that returns a value that you can store in a variable.  Function, just like commands, may require some extra information that is placed in ( ) and separated by commas.  In other words, you can say this:

MoFo = sqr(4)

Which means MoFo is equal to sqr(4), the square root of 4.

But you can't do this, or at least not have a reason to:

MoFo = Response.End

This is because Response.End is not a function, it is a command, it does not return a value that MoFo can equal to.
