When it comes to Twitter fails, no one did it more than Piers Morgan in 2014.

Once Piers got fired from CNN, he found himself with a lot of time on his hands and Twitter up on his computer.

The Brit showed just how thin his skin was on the social media site.

He went after Larry King

He went off CNN, Jeff Zucker and Anderson Cooper

And then Larry king again

He then picked on English Broadcaster Jeremy Clarkson.  

Then back to Larry King

You get the idea. Morgan is so bitter about getting sacked at CNN and he wants each and every one of his Twitter followers to know it.

The best thing Piers could do in 2015, delete his Twitter account and never go back.
