Start singing "Highway to Hell" when Frodo and Sam approach Mt. Doom

Start singing "Great Balls of Fire" when Denethor jumps off that cliff

Cry and snif loudly on every, even the least emotional scene

[Falcon]

When Frodo get his finger bitten off yell out, "Needs some ketchup."

11. In TTT when the Ents decide to march to war, stand up and shout "RUN FOREST, RUN!"

Lol, the one who found that one can be proud, it's smart yet funny
