If you watch carefully Riker opens his eyes in the end scene when he's supposed to unconscious.
Three quarters of the way through the episode, Dr Kathrine Pulaski makes a Medical Log (Supplemental) entry. As she does so, although the Enterprise is supposed to be in the vicinity of a distant uncharted planet, the shot of the Enterprise in orbit clearly shows North America on the planet surface.
Geordi wears absolutely no protective gear when he and Data go back down to the planet to get a sample of the plant that attacked Riker.
Riker: Captain, one of the things I've learned on these voyages and so on this ship and from you...is that most lifeforms act out of an instinct for survival--not out of malice.
Pulaski: I just want to be certain you still know who you are.
Riker: Of course I know who I am - I'm Captain Jean-Luc Picard of the USS Enterprise.
Picard: (joking) I'm delighted that you are feeling better, Captain. The Admiral and I were worried about you.
Data: Captain, I do not believe you have the authority to promote me to the rank of Admiral.
(while Riker is scanned by a medical assistant)
Riker: This bug is persistent, I'll admit that. But I'm not worried. We Rikers are ornery, too. As a matter of fact, my great grandfather once got bit by a rattlesnake. After three days of intense pain...snake died.
This is the only episode in the series to contain both Gates McFadden (Dr. Crusher) and Diana Mulder (Dr. Pulaski), although McFadden only appears in stock footage.
The writer's strike affected the number of episodes shot in the second season. There were only 22 episodes made while all other seasons had 26 episodes.
Worf (Michael Dorn) does not appear in this episode.
This episode marks the final appearance of Dr. Katharine Pulaski (Diana Muldaur) on the series.
This episode developed as a means to save time and money due to the ongoing writer's strike at the time. It is (to date) the only "clip show" - an episode that showcases clips from previous stories - within any of the Trek series. Due to its strained nature, it ranks on many fans' "least favorite episodes" lists.
