Given that Twitter may not be long for this world, I thought I may as well share this Google doc I put together containing every post from Marc Laidlaw's Breengrub account. I originally made this for my own personal use so I could more easily reference the information for fanfiction writing purposes, but now it may be a matter of preservation as well, which means everyone deserves to have access to it.

Made this in Photoshop when I was just a little baby teenage Half-Life fan. The late 2000s sure were a different time, but the memes and my love of Half-Life remain.
