object used in example but not created there

[RafalSkolasinski]

In here object s is used in the example but not created on this page (at least in this form).

Above it is created as series

In [8]: s = pd.Series([1, 2, 3, 10, 20, 30], lst)

once under here

In [27]: s
Out[27]: 
first  second
bar    one      -0.575247
       two       0.254161
baz    one      -1.143704
       two       0.215897
foo    one       1.193555
       two      -0.077118
qux    one      -0.408530
       two      -0.862495
dtype: float64

is completely different thing.

I find referring to objects created on other manual pages very confusing.

The Series is created on line 260 in doc/source/groupby.rst, but the creation was hidden. A pull request to make that visible would be great if you could.
