After my earlier post, it looks like the prototype of the above line came from a Canadian reader of mine, John Gross, way back before the inauguration:

Mr Gross last featured at NRO over an all-purpose stump-speech line he concocted:

His jokes are beginning to develop an alarming habit of coming true six months later.
