GTA 5 mod makes characters ragdoll all the time
Ragdolls acting inappropriately is one of gaming's most amazing sights. This is especially true when GTA 5 is involved.
GTA 5's first ragdoll mod is here. The aptly named Ragdoll on Demand makes sure the characters' ragdolls are always active. This applies to cutscenes too since GTA doesn't pre-render them, which means all serious story beats can be interrupted with people falling to the floor for no particular reason.
YouTube channel Tyrannicon has a video showing the madness that ensues. It's hard not to laugh.
