Deleting an info_ff_script?

[Bridget]

I have multiple instances of the same script in my map. When the player touches one of them, that specific one should disappear (get removed). How do I delete the info_ff_script? RemoveEntity(self) doesn't work and OutputEvent("","Kill") would require I make a different script for each instance in the map (50+).

a_special_script = info_ff_script:new({
	name = "A script!"
	touchflags = {AllowFlags.kOnlyPlayers,AllowFlags.kYellow},
	model = "models/items/ball/ball.mdl"
})

function a_special_script:touch(touch_entity)
	if IsPlayer(touch_entity) then
		-- remove the specific script touched here.
	end
end
