And you gotta love Fuse’s labels, particularly the first one (Metaphorical Scrotums). Which, to be sure, sent me to look for the proper plural form; Merriam-Webster Online gives “scrota” first but “scrotums” as an alternative, so Fuse as usual gets full approval. (Yes, Wiktionary shows up first at Ask–but I trust M-W for the usual reasons.)
OK, here’s a bizarre one: “plural of scrotum” as a Google search. The first result is from Google Book Search; clicking on that yields 232 results…and a context-sensitive ad that I won’t mention here.
