So, here's what I entered.
My headcannon is that the Normandy crew started up a tradition to unwind between missions: Movie Night. And after watching certain really old vids, some of them keep quoting lines for days afterward.
Joker: "I wouldn't say this thing thinks it's Satan. I'd say it is Satan!"
Zaeed: "Well, Satan ... is in DEEP SHIT!"
Shepard: "We're gonna need bigger guns."
Garrus: "Very, very big FUCKING GUNS!"
... Which prompts Dr. Chakwas to wonder if a round of psych evals is in order. XD
Hahah ... and if anyone's wondering what movie they're quoting above, it's pretty much the last gasp of the 1980s-style bad (yet in this case, awesome) action movies.
