Casting asparagus, anonymously or otherwise, is preferable to casting aspersions, and much tastier.
I personally like pickled asparagus. It's damn fine eatin'.
I believe some anonymous asparagus (asparagi?) were cast in the video production VeggieTales?. Does that count?
Yep! Ma and Pa Asparagus, Junior Aspargus (a major character, no less), and that guy with the monocle who plays Alfred in the Larry-Boy series.
