Can you play the pipe?

Peter Piper can.

Or perhaps you can pickle peppers?

Peter Piper can do it too.

And please, can you pick a peck of pickled peppers as Peter Piper did?

And now, can you say that altogether?

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?

This is a tongue twister. 

Now it's your turn to say it loud and clear.

Or not that clear.
