Oaf who

There once was a lemon-green oaf who
Was also a nice white sliced loaf who
Said "Four curried fleas
And a whole load of cheese!"
And filled up his wellies with tofu.

There was also a loud ambiguity
Who ate laundry with assiduity
'Twas a British Rail sandwich
That got out of hand which
Reduced it to mauve superfluity.
