Reversible Process Puns

Noted researcher Rosemary Fuller was involved in a lab accident today. She's working on the theory that herb-based formulas can actually reverse or accelerate the aging process. Parsley, for example, has been shown to cause rapid aging, and recent efforts have shown good results with oregano-based anti-aging serums. Ms Fuller was, unfortunately, standing near a vat of simmering oregano serum when a nearby researcher nudged her and she fell in! It appeared at first that the anti-aging serum would cause her to de-age down to nothing. Now, though, it looks like she'll be all right. The Parsley's aged Rosemary in time.

That would be grape.
