Where does Python's pydoc help function get its content?

I have a lot of callable objects and they all have the __doc__ string correctly filled out, but running help on them produces the help for their class instead of help based on __doc__.

I want to change it so that running help on them produces customized help that looks essentially like what I would get if they were actual functions instead of instances of a class that implements __call__.

In code, I'd like to make the output of this:

class myCallable:
    def __init__(self, doc):
        self.__doc__ = doc

    def __call__(self):
        # do some stuff
        pass

myFunc = myCallable("some doco text")
help(myFunc)

Look more like the output of this:

def myFunc():
    "some doco text"
    # do some stuff
    pass

help(myFunc)
