Ducks in a row

I love this expression. Getting your ducks in a row. It's ridiculous to think about. What if you don't have ducks? And even if you had ducks I feel like they would be difficult to get in a row. Unless it's a mom duck with her baby ducks, in which case it happens naturally, so you wouldn't have to do anything to get the ducks in a row.

Anyways...I'm trying to get my ducks in a row for this weekend and it's a little challenging considering I've got about 20 to organize....
