Arnold posted video of himself Wednesday, which shows him pulling into Dodger Stadium to receive his vaccine for COVID. You see him sitting passenger-side in an SUV as a medical staffer sticks with a needle and injects the serum ... Arnold, of course, didn't flinch.

It's funny ... he dropped two famous movie lines of his during his vaccination -- a well-known one from "Terminator 2: Judgment Day" and a more obscure one from "Jingle All the Way." If you're a die-hard Arnold fan, you know both off the top ... but it's unclear if his vaccine giver did.

He tells her to "put that needle down!" as she's injecting him, which is a reference to 'JATW' when he told his schmucky neighbor, Ted, to put the cookies down that he was salivating over. The woman doing the deed didn't seem to respond to it, though 😅

Then came the more iconic Arnold line in the aftermath ... "Come with me if you want to live," which is what the Model 101 Terminator told Sarah Connor in the legendary sequel.

That quote is probably more relevant, but in any case ... AS gives a ringing endorsement of the vaccine, and invites everyone who's eligible to come get one ASAP.
