Bok choy, pak choi or pok choi (Chinese: 上海青; pinyin: Shànghǎi qīng; literally: ``Shanghai Green''; Brassica rapa subsp. chinensis) is a type of Chinese cabbage. Chinensis varieties do not form heads and have smooth, dark green leaf blades instead, forming a cluster reminiscent of mustard greens or celery. Chinensis varieties are popular in southern China and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. This group was originally classified as its own species under the name Brassica chinensis by Linnaeus.

Take Your Dog to Work Day (TYDTWDay) was created by Pet Sitters International and first celebrated in 1999. PSI created the day to encourage businesses to allow dogs in the workplace for one Friday each year to celebrate the great companions dogs make and promote their adoptions from local shelters, rescue groups and humane societies. PSI believes that through the event dog-less co-workers will be encouraged to adopt when they witness the human-animal bond. The week leading up to Take Your Dog To Work Day is Take Your Pet To Work Week. Take Your Dog to Work Day and Take Your Pet to Work Week are registered trademarks of Pet Sitters International, Inc.
