Not really a glitch just a very amuzing and wierd thing.
In half life you pin an enemy, wait for it's body to become still ,then shoot the body again with the crossbow , but shoot it so it pins to another surface or wall, the bolt should go through the body not hit it. But if you hit it with the crowbar or shoot the body after you shoot the bolt it will start spazzin because it's trying to get to the area where it's been pinned but it's been held by another bolt already. Enjoy! :] (the farther apart the bolts are the more the body will spaz)
