Tongue twisters of the week...

Can you say these words without stuttering ( sans bégayer) ???

'' Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers,
Where's the peck of pickled peppers Peter Piper picked?''

''  I saw Susie sitting in a shoe shine shop.
Where she sits she shines, and where she shines she sits.''
