 Question: can you have a heart attack from laughing Context: Knight auditioned for the show, expecting a one-season run. In 2007, Knight's co-star Isaiah Washington (Preston Burke) insulted him with a homophobic slur, which resulted in the termination of Washington's Grey's Anatomy contract. In 2009, after the conclusion of the fifth season, it was confirmed that Knight would not be returning for the show's sixth season. The actor stated the reason for his departure was due to a ``breakdown in communication'' with Rhimes, his character's lack of screen time, as well as his decision to come out as openly gay. Knight received generally positive reviews for his performance as O'Malley, and garnered a nomination for Outstanding Supporting Actor in a Drama Series at the 59th Primetime Emmy Awards. Despite this, his death received mixed feedback.
 Question: does george ever come back to grey's anatomy Context: A queen ant (formally known as a gyne) is an adult, reproducing female ant in an ant colony; generally she will be the mother of all the other ants in that colony. Some female ants, such as Cataglyphis cursor, do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning, and all of those offspring will be female. Others, like those in the genus Crematogaster, mate in a nuptial flight. Queen offspring develop from larvae specially fed in order to become sexually mature among most species. Depending on the species, there can be either a single mother queen, or potentially, hundreds of fertile queens in some species. Queen ants have one of the longest life-spans of any known insect -- up to 30 years. A queen of Lasius niger was held in captivity by German entomologist Hermann Appel for 283⁄4 years; also a Pogonomyrmex owyheei has a maximum estimated longevity of 30 years in the field.
