Blackheath

I don't remember the author of this poem, but it is not me. I thought you might get a chuckle.

I met a man from Blackheath

Who sat on his set of false teeth

Said he with a start, O lord bless my heart

But I've bitten myself underneath.

How's this for a tongue twister:

Thadius Theopholis Thiste, the thistle sifter, thrust three thousand thistles through the thick of his thumb.

Or this one:

The skunk thought the stump stunk,

but the skunk thought the stump stunk.

This one is supreme:

Sue sold six silk sheets to six sheiks at her sea side silk sheet store.
