How to add a title to Seaborn Facet Plot

How do I add a title to this Seaborne plot? Let's give it a title 'I AM A TITLE'.

    tips = sns.load_dataset("tips")
    g = sns.FacetGrid(tips, col="sex", row="smoker", margin_titles=True), "total_bill", "tip")


After those lines:

    g.fig.suptitle('THIS IS A TITLE, YOU BET') # can also get the figure from plt.gcf()

If you add a suptitle without adjusting the axis, the seaborn facet titles overlap it.
