 Question: can you have a heart attack from laughing Context: A pteridophyte sensu lato is a vascular plant (with xylem and phloem) that reproduces via spores, and therefore was a member of the former and now invalid taxon Pteridophyta. The term is now used only informally to denominate a fern (monilophyte) or lycophyte. Because pteridophytes produce neither flowers nor seeds, they are also referred to as ``cryptogams''. The pteridophytes include the ferns, horsetails, and the lycophytes (clubmosses, spikemosses, and quillworts). These are not a monophyletic group because ferns and horsetails are more closely related to seed plants than to the lycophytes. Therefore, ``Pteridophyta'' is now an invalid taxon, although the term pteridophyte remains in common parlance, as do pteridology and pteridologist as a science and its practitioner, to indicate lycophytes and ferns as an informal grouping, such as the International Association of Pteridologists and the Pteridophyte Phylogeny Group.

Jenna Fischer's pregnancy was written into the show, and Pam was again pregnant at the start of the season with a boy as she was in real life. Unlike the sixth season, there was no episode focusing on the baby's birth; it was instead announced on a blog. In an interview, executive producer Lieberstein stated that, with the departure of Michael Scott, the writers would explore further into the other characters on the show, such as centering on a specific character for an episode. On January 25, 2012, news broke that NBC was planning a spin-off series starring Rainn Wilson as Dwight Schrute, that would be set at Schrute Farms, Dwight's bed-and-breakfast and beet farm. The spin-off would be created by Wilson and executive producer Paul Lieberstein, but Office developer Greg Daniels would not be involved. Due to his initial involvement in the spin-off, Lieberstein stepped down as showrunner of The Office. On October 29, 2012, it was revealed that NBC was not going forward with the proposed spin-off, although the original backdoor pilot, ``The Farm'' aired later in the ninth season.
