These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Funny - Many, but special mention must go to "BECAUSE YOU ARE HEADCRAB ZOMBIE"
but this is our house :(
"DARKMAN YOU WILL SUFFAR!"
"Combine came and put science in me and made me big and strong!"
The science flew off Gordon Freeman's face.
Pants.
"I know bro but you are hero" John Freeman said back to comfart Gordon." In Djy's vid, the actual fart during that line and the face John does is priceless!
Another one: At some point during Free Man, John Freeman goes on killing Combines with barebear hands! (This was even noted with a clever Visual Pun on Djy1991's machinima) Some years later, a new pair of "boxing gloves" for the Heavy were added into Team Fortress 2: They are a pair of severed bear hands!
Gordon Freeman's really actually final last death.
In the machinimas:
Alternate Character Interpretation - In the Djy version, the Dark Man is the same person as revived Gordon Freeman. In the Gaz version, they're two separate people.
Big Lipped Alligator Moment - Plenty in the original writings, but the machinimas take this trope to extremes.
In the Djy1991 adaptation of Free Man, they added in a scene that lasts from 6:12 to 11:38, where they deviate from the original, making John Freeman into a badass god figure by showing him fighting through a number of memetastic locales. While it was praised by some viewers, others felt that it added nothing to the video.
Within that segment, while most of the fighting was more or less in line with the rest of the story and John Freeman's larger-than-life image, there is an indisputable BLAM when the G-Man, who has a Hitler mustache, shows up and kicks John Freeman into the sky, before turning into Saxton Hale. John Freeman goes flying over various locales from assorted Source-based games such as cp_gravelpit, ctf_convoy_v2 and gm_bigcity, ultimately landing in GLaDoS's main chamber, where John Freeman gets into a one-sided argument with her, blows her up and arrives back at the Citadel just in time to see the humens at safe place before the Citadel explods.
"the countrysides were nice and the plants were singing and the birds and the sun was almost down from the top of the sky."
