Can you put in the missing words? Here they are: wife, eat, clean, lean, two

Here are the completed lines and the full nursery rhyme:

• Jack Sprat could eat no fat,
• And his wife could eat no lean
• And so betwixt the two of them
• They kept the platter clean

The whole nursery rhyme is:
Jack Sprat could eat no fat,
His wife could eat no lean,
And so betwixt them both, you see,
They licked the platter clean.
