Object coming before the verb?

In the Jewel song Sara Swan Sleepyhead we have this passage:

There’s a knock at the door
A funny suit Sammy wore
And on his face an ear to ear grin

The bolded part seems weird to me. Is this correct grammar, and how common a usage is it?

Solution 1:

It is called inversion, this case inversion of the position of the object with the rest of the sentence. It can be used for emphasis of the phrase in first position and it is correct. It is unusual, but not exactly rare.

Solution 2:

I suspect the purpose of inversion may be to create an assonance "door"/"wore" for lyrics and song purposes. May it be so ?
