Mr. See owned a saw

And Mr. Soar owned a seesaw

Now, See's saw sawed Soar's seesaw

Before Soar saw See

Which made Soar sore

Had Soar seen See's saw

Before See sawed Soar's seesaw

See's saw would not have  sawed Soar's seesaw

So See's saw sawed Soar's seesaw

But it was sad to see Soar so sore

just because See's saw sawed Soar's seesaw

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?

If you understand, say "understand"

If you don't understand, say "don't understand"

But if you understand and say "don't understand"

How do I understand that you understand? Understand?
