The Purple Menace

Ethel wasn't 100% sure that this was the cauliflower of her dreams. She decided to give another two or three good pokes. Then she put it back on the shelf and picked its neighbour. She had a good feeling about that one. She examined it carefully and gave it a good poke. And another. And another. And a little squeeze to be absolutely sure that this unfortunately wasn't The One either.
Pah, she had all the time in the world. She would poke to her heart's content until she'd find a vegetable that made the grade.
Or not.
