Dangerous tongue twisters:

I am not the pheasant plucker,
I’m the pheasant plucker’s mate.
I am only plucking pheasants
Because the pheasant plucker’s late.

I slit the sheet, the sheet I slit;
and on the slitted sheet I sit.

I’m not the fig plucker,
Nor the fig pluckers’ son,
But I’ll pluck figs
Till the fig plucker comes.
