I love Burns although I have read that he really did love the ladies. Maybe a little too much.
Well, put it this way... He had three daughters named Anne -- that he acknowledged.
Thing is, the man dropped the F-bomb in his works.... Take, for example his "Ode to Spring":
When maukin bucks, at early f***s,
In dewy grass are seen, Sir,
And birds, on boughs, take off their mows
Among the leaves sae green, Sir;
Latona's sun looks liquorish on
Dame Nature's grand impetus
Till his p***k go rise, then westward flies
To roger Madame Thetis.
(Rather appropriately, I just realized, "maukin" is a variant of "malkin" which was Scots dialect for several off-color things.)
