So if your singular words possess,
You have to add apostrophe-s.
But if it’s plural words you see,
You need s-apostrophe.
This rule's reliable unless
A plural doesn’t end in s.
Then you must add apostrophe-s.
3. If a room is shared by brothers,
That's s-apostrophe.
That's what we want to see,
That s-apostrophe.
If the room just belongs to one,
Apostrophe-s is how it's done.
That's how it's always done.
[Refrain]
4. If the guys own a fancy car,
That's s-apostrophe.
That's what we want to see,
That s-apostrophe.
If the car just belongs to one,
Apostrophe-s is how it's done.
That's how it's always done.
[Refrain]
