Tongue twisters can be quite tricky to say. This is especially true when they are uttered quickly. The following are a few popular English tongue twisters:
She sells seashells by the seashore.
The shells she sells are surely seashells.
So if she sells shells on the seashore,
I'm sure she sells seashore shells.
The sixth sheik's sixth sheep's sick.
If you keep a lot of liquor in your locker
It is wise to put a lock upon your stock
Or some fellow who is quicker
Will trick you of your liquor
If you fail to lock your liquor with a lock.
Peter Piper picked a peck of pickled peppers.
How many pecks of pickled peppers did Peter Piper pick?
If Peter Piper picked a peck of pickled peppers,
Where's the peck of pickled peppers Peter Piper picked?
I'm not a pheasant plucker, I'm a pheasant plucker's son.

The first and fourth tongue twisters are especially well-known. A peck is the equivalent of two gallons which is a little less than 9.1 litres.
