一、在英美等許多西方國家常用繞口令來判定汽車駕駛員是否是酒后駕車。如：
Cat,cat,catch that fat rat.
Where are you going, my little cat?
I’m going to town to buy a new hat!
What A hat for a car?
A cat with a hat?
Who ever heard of a cat with a hat?
二、在挑選演員時，導演或主考人經常要求報考者朗誦一些繞口令。如：
When a doctor doctors another doctor, does he doctor the doctored doctor the way the doctored doctor wants to be doctored, or does he doctor the doctored doctor the way the doctoring doctor wants to doctor the doctored doctor?
