　　Try the following tongue twisters and have some fun.

　　1. The sixth sick Sheik's sixth thick sheep.

　　2. This is a zither. Is this a zither?

　　3. I thought a thought.

　　But the thought I thought

　　wasn't the thought I thought I thought.

　　If the thought I thought I thought had been the thought I thought,

　　I wouldn't have thought so much.
