Frozen crewwoman in shower 

This sciences division crewwoman was found dead by Geordi La Forge in the same crew quarters. He discovered her in the shower with her clothes on. La Forge contracted the polywater intoxication after catching this crewwoman who had fallen out of the shower, when he placed his hand on the shower wall to stand back up. 

Later, while determining the cause of the intoxication, William T. Riker recalled an instance of someone showering with their clothing on in the library-computer, who was later determined to have been discovered by the original  on Psi 2000, and had died under similar circumstances. The mention of La Forge's note of the crewwoman taking a shower with her clothes on triggered Riker's memory enough for Data to discover the cause of, and for Dr. Crusher to discover the subsequent cure for, the intoxication.
