An update to the timeless classic:

My chemistry teacher did a demo.
But sadly had no clue,
That what he thought was H₂O,
Was Hg(CNO)₂.

[GOP_Party_Animal]

Willie was a scientist
Willie is no more
Because what Willie thought was H2O
Was H2SO4

[LonePalm]

Alas poor Phil
His face we see no more
For what he thought was H₂O
Was H₂SO₄

Garde la Foi, mes amis! Nous nous sommes les sauveurs de la République! Maintenant et Toujours!
(Keep the Faith, my friends! We are the saviors of the Republic! Now and Forever!)

What movie is that scene from?
