problem using Linecollection

I'm simply trying to draw a couple of lines using line collection, not sure
why it doesn't work

import matplotlib.pyplot as plt
from matplotlib import collections as mc
import numpy as np
import pylab as pl

segments = [ [(1,2),(3,4)],
        [(5,6),(7,8)] ]
lc = mc.LineCollection(segments, linestyles='solid', pickradius=5, zorder=2)
fig, ax = pl.subplots()

ax.add_collection(lc)
ax.autoscale()

What is not working?

import matplotlib.pyplot as plt
from matplotlib import collections as mc
import numpy as np

segments = [ [(1,2),(3,4)],
             [(5,6),(7,8)] ]
lc = mc.LineCollection(segments, linestyles='solid', pickradius=5, zorder=2)
fig, ax = pl.subplots()

ax.add_collection(lc)
ax.autoscale()

plt.show() # added this line to get window
fig.save('so.png') # to save as png

gives me the attached figure.
