I watched Lord of the Rings: The Two Towers a few days ago. And for some reason, when Sam gave this speech, I thought of FIM. It may not be as grand or as epic as Lord of the Rings, and it may border on the outright silly sometimes; but in its own right, it is indeed one of the Tales that Really Matter.

Note: PAV:=Pony Audio Video. Like a PMV, it requires the use of visual clips of My Little Pony: Friendship is Magic accompanied by audio from a different source. The key difference is that a PAV can be speeches, poems, etc. In fact, I guess PMV's are a kind of PAV, but more specifically music. This PAV just happens to have background music, since it isn't removable from the source audio.
