*The icon used for Hammer's obsolete entities consists of what presumably is the head of Jay Stelly pasted on the WikipediaFileFonz Pic.PNG|bust of WikipediaFonzie|Fonzie from the TV sitcom ''WikipediaHappy Days|Happy Days'', with his trademarks thumb up and leather jacket.

*A line in the file "sdk_weapon_parse.cpp" from the http//github.com/ValveSoftware/source-sdk-2013 2013 edition of the Source SDK features a nod to WikipediaDouglas Adams|Douglas Adams, author of the series ''WikipediaThe Hitchhiker's Guide to the Galaxy|The Hitchhiker's Guide to the Galaxy'', and its number WikipediaPhrases from The Hitchhiker's Guide to the Galaxy number 42|42 "m_iDamage = pKeyValuesData->GetInt("Damage", 42) // Douglas Adams 1952 - 2001".

==Half-Life 2 leak|''Half-Life 2'' leak==
*When first launched, the Valve Hammer Editor featured in the Development of Half-Life 2 game|''Half-Life 2'' leak plays a 3 seconds WikipediaMusical Instrument Digital Interface|MIDI intro of the song "WikipediaU Can't Touch This|U Can't Touch This" by WikipediaMC Hammer|MC Hammer (named "hamrtime.mid"), an obvious play on the name of the artist, and the infamous sentence featured in the song, "Stop... Hammer time!".

*There is a line{{abbr3|i|temp/hl1hazaudio/oldhaz_barney/tr_ba_superfly.wav}} that  was to be said by a security guard in a port of the Hazard Course from the original game. The line is "''Sorry, sir. You know I can't let you through here without your good friend Superfly Johnson. Wa hah. Just kidding, Gordon. You go on through. Hah haha!''". This is a reference to Superfly Johnson character from the video game ''WikipediaDaikatana|Daikatana'', best known for his poor pathfinding skills. He is an ally, and has to follow the player through some levels. If the player reaches a loading point and the character is not with the player, the player character will say "''I can't leave without my buddy, Superfly!''". It also a reference to a line{{abbr3|i|barney/c1a0_ba_hevno.wav}} said by the security guard when Gordon tries to go through a checkpoint without his suit on. The line is "''Sorry, Mr. Freeman, I got explicit orders not to let you through without your hazard suit on.''"
