Reverend's Easter

The reverend,
Or the Rev,
As he liked to be called.
Offered his wife,
Who shall henceforth be referred to as 'Rev's Wife' as she's not very important,
A full rundown of his expectations.
'Much like Jesus,'
He said,
'I'm going to be needing to eat nothing but chocolate eggs for two weeks.'
Rev's wife couldn't be bothered to argue,
And plodded off to Sainsbury's.
