A tongue twister

 This is a slightly different version of the tongue twister I taught you today you can see in Singin' in the Rain:

The classic version goes:

Moses supposes his toeses are roses,
but Moses supposes erroneously;
for nobody's toeses are posies of roses,
as Moses supposes his toeses to be.

The film version goes:

Moses supposes his toeses are Roses,
But Moses supposes Erroneously,
Moses he knowses his toeses aren't roses,
As Moses supposes his toeses to be!
