This is silly but why not:) I recently watched this delightful movie with Danny Kaye and have been thinking since whether we can do justice to this line in Quenya:

The pellet with the poison is in the vessel with the pestle but the chalice from the palace has the brew that is true.

Here are two variants I have come up with - neither of them are truly satisfactory (they don't have the same tongue-breaking quality) so here's a challenge maybe you can come up with a nice one!

I hlókea hloima ná mi yulma as i turma mal i sulpava salpa same i sáva ya mára.

I sungwa as i sangwa tana tantava tanna mal i toina tolpo hepe i poika pirya.
