In the Garden of Light and Shadow

[Gremzin3]

I’m a pheasant plucker,
I pluck mother pheasants.
I’m a very pleasant mother pheasant plucker.

Another version of this tongue twister I was taught at a very young age. Best repeated two or three times for best effect.

I'm not a pheasant plucker
I'm a pheasant plucker's mate
I'm only plucking pheasants as the pheasant pluckers late.

It’s a classic vocal warmup exercise. Either version should be repeated quickly 10 times - a challenge that’s a delight to present to someone tired or drunk!
It never fails to get a reaction.
