My dad used to quote a poem he learned in school.
This is it:
Theophilus Thistle, the Thistle Sifter, Sifted a sieve of unsifted thistles.
If Theophilus Thistle, the Thistle Sifter, Sifted a sieve of unsifted thistles,
Where is the sieve of un-sifted thistles Theophilus Thistle, the Thistle Sifter, sifted?
