more tounge twisters !

As we were posting about tounge twister I found more and I will post them, and you can try to say them.

We start with an easy one:
Kanta is a masai girl, she can tie a tie and untie a tie, if kanta can tie a tie and untie a tie, why can't I tie a tie and untie a tie?

Suddenly swerving, seven small swans
Swam silently southward,
Seeing six swift sailboats
Sailing sedately seaward.

...and the most difficult is:
Suzie, Suzie, working in a shoeshine shop.
All day long she sits and shines,
all day long she shines and sits,
and sits and shines, and shines and sits,
and sits and shines, and shines and sits.
Suzie, Suzie, working in a shoeshine shop.
