My (point to chest) hat (both pointer fingers form a hat on head),
it has three (show number 3) corners (point to elbow),
Three (show number 3) corners (point to elbow)
has my (point to chest) hat (both pointer fingers form a hat on head)
And had it not three (show number 3) corners (point to elbow),
It would not (shake head "no") be
my (point to chest) hat (both pointer fingers form a hat on head).

And had it not three corners,
