A scientist in AM has a rather hilarious rant about how all he does is push buttons and stare at screens. Then he implies that he hasn’t taken time off in 25 years.
Edit: Sniper09, that was there in HL1 too. It’s the order that you have to go through the portals in.
Another movie reference - Back to the Future. [COLOR=‘DarkRed’]1.21 GW !!
I found a somewhat disturbing reflection (face) in one of the shut-off monitors at c3a2f. This is not a permanent picture, but a result of light-reflection or something that only appears, when you stand in the right angle. I’m not sure if this was actually intended, or rather a kind of freak-of-nature thing:
Next one isn’t hidden or anything, I just found it to be funny that the waste shredding machinerie has a dial-plate (counter-clockwise also) and a very fucked up keyboard 
Last one is not that spectacular, but instantly reminded me of Lost. Could be on purpose. After all, there are Lost-References in Portal as well:
Something that me lol 
As a Brit seeing a chuckle brothes mug made me smile. it was at the bit with the lift and all the headcrabs.
oh, those are everywhere
Just after the major marine skirmish in “Questionable Ethics”, as the bodies litter the floor and the scientist comes in he exclaims, “Look what you did…I can’t BELIEVE what you did!”

It was such a subtle reference, but my God I’m in love with the devs right now.
Just noticed one of the Spin signs in AM says “Our track system is really cool!”
Damn I wanted to post this one, nice find man!
The scientists in Anomalous Materials who discussed whether an improved version of an existing project could be considered a work of art made me chuckle - meta!
I love all the little references in the dialogue, like security guard that questions you whether it was really necessary for me to spend that hour in the hazard course, and the one who said it was a shame you let the ponytail go.
Although was anyone else than me disappointed by the fact that it’s a security guard’s casserole you blow up - not Dr Magnusson’s?
No, it was Magnusson’s. Did you not get the reference to leave because he’d be returning?
Ah, no, I must have missed that line. Everything is in order then
I took pics of a few, haven’t seen this one shared anywhere yet
Wallace Breen’s to do list

"Plans to take over the world By: Wallace
Step 1: meet aliens
step 2: be -theyre- their friend
step 3: live in a big tower so me -enumee- -enam- enemies cant get me.
step 4: Eli cant come because hes a stupid-face
Eli is saying ‘My daughter is cooler than you’
The other picture is of Breen in his tower with bullets bouncing off from the plane"[/b]
Then I like this on the books
That one of the control panels out of ep2 I think.’
EDIT: Wait no Hang that’s different
That’s the code for the portal puzzle. Found somewhere else as well.
This must have been posted somewhere else though I haven’t found it. This made me chuckle though.
So at some point I realised the amount of monitors at each workstation was increasing to ridiculous levels. It wasnt til it got to 5 monitors that I took a screenshot;
and then a bit later I noticed one with 7 monitors, lol… overkill;
The monitor on the controls in the surgery room (and other places) are scrolling the lyrics to https://www.songmeanings.net/songs/view/3530822107858640685/
What do you mean by writing the lyrics. Is it on a monitor or what?
Er, yeh on several of the control panel monitors in the game, those song lyrics scroll past.
Stuff i found
