Good point. One possibility is to source every episode which *doesn't* show this happening, which is somewhat burdonsome.
Especially in Star Trek, where you would have to review several hundred hours of material to verify that something didn't happen.
Another is to say that it *did* occur twice (and source the episodes); discovery and proof of other occurences is left as an exercise the reader. The third option is to find a secondary source which claims this, and (again) let the reader determine if it's valid or not; after all, we don't present The Truth, only what is verifiable
This is quite feasible. In the case of Star Trek, there are excellent episode and continuity guides available for at least the first four series, etc. Much of the trivia on our articles seems to be derived ultimately from anecdotes recounted in these guides, but not attributed.
