When Alfred was witty

Alfred, the pianist who insist he is not my father
Told me he could walk on water,
to prove it we went to where the water is shallow
he sank slowly, legs, torso and his head
I was not unduly worried,
at the bottom, he walked back to shore
and I gave him back his alpaca and French Beret, but I said nothing
he hadn't stepped on water only walked on it.
He borrowed my shoes to get home I; his son had to walk barefoot
and he never returned my shoes
