Spoofs La Femme Nikita (1997), a hit show which had premiered 4 months prior. Nikita would often be seen dangling from the ceiling with a flashlight. when breaking into places on clandestine missions. There is such an Ellen scene here, searching for gauze in the linen closet. Incidentally, one iconic episode which has Nikita dropping in such way from the ceiling---sans flashlight---is Choice (1997), and it eerily aired just one day before this Ellen title did. (Most likely, that Nikita scene had been part of season one promos, early on.)
Filler episode, per title, it shows clips from many previous Ellen episodes.
