4. Piers Morgan
One of the very few celebrities considerably more intolerable than Lord Sugar on Twitter is the man he's always arguing with - Piers Morgan. The television host has turned into a worse clone of the aforementioned, and takes to Twitter to talk football, celebrities, and dreadful jokes - while revelling at being hated by the masses. Piers is an Arsenal fan, and therefore spends a lot of time tweeting jokes about London rivals Tottenham, which is cringe-worthy enough as he's shown his lack of football knowledge many times before. If he isn't arguing with Lord Sugar, he's having to defend himself after not thinking before he tweets, which subsequently leads to his followers on his case - more often than not about a football matter. He always has his nose in other sports, and has an opinion about absolutely everything - regardless of whether or not he knows what he's talking about. Piers very rarely has his moment on Twitter, but such incidents are few and far between when he does, and it certainly doesn't last long with how much time he spends on Twitter talking nonsense. A smug, pompous know-it-all is the man he comes across as, and one many would like to see wiped off the face of the earth given the chance.
