Piers Morgan skin seems to be getting thinner by the day. 

The failing CNN anchor has turned his attention away guns and calling FTVLive a mad blogger to take out some of his frustration on the guy he replaced, Larry King.

Last night Morgan was on one of his Twitter rants dissing King every chance he got.

Morgan answered one tweets about Larry King with the reply "Larry who."

King recently said that CNN has problems and might be better off just running episodes of Sponge Bob.

Morgan has watched his ratings fall since taking over for King and as FTVLive FIRST reported, CNN boss Jeff Zucker is looking to pull the plug on Morgan at 9PM on CNN.

Larry King might be old, but it's Piers Morgan thats bitter.
