[[https://www.youtube.com/watch?v=dxq8fKbWJbE Jamie's Mod]] is [[MindScrew a,]] [[SurrealHumor uh,]] ''strange'' GameMod of {{VideoGame/HalfLife}} in development under [[https://www.youtube.com/user/lemurboy123 lemurboy123]] and [[https://www.youtube.com/user/HellFire23452 HellFire23452]] and inspired by various in-jokes from the two and their peers, as well as their YouTube followers. Various enemies and characters are replaced by strange figures such as the bad-mouthed, synthesiser-voiced [[https://www.youtube.com/watch?v=tcmhdnLAk04 Jamie]], as well as characters like WesternAnimation/{{Shrek}}, [[{{WesternAnimation/JimmyNeutronBoyGenius}} Carl Wheezer]], and the ever-hungry [[https://www.youtube.com/watch?v=_8Ctwl63XCg Pumkin]]. The weapons have also been refitted with custom textures and sounds, such as [[ImprobableWeaponUser a dog and an RPG launcher that shoots the phrase "OH NO".]]
