interrupting cow

I doubt that I'll ever remember now 
the thing I was just 
(or not) about 
to do 

or say, let's table that
anyhow - since you interrupt, well 
what can I do for you? you

cheeky moo. Oh, bah 
he oinked. As if

this Old MacDonald
had a shit to give

to fit your bovine ass.
No mind! What is it?
Whatever, forget it I bet 
it too shall pass.
