5. Lord Sugar
That man off the apprentice, yes. Lord Sugar, as he's now known by, frustrates the masses with his daily idiocy. Whether it's him eavesdropping on another celebrity's argument (often involving Piers Morgan), and subsequently embarrassing himself, attempting football banter and failing greatly, or his old man jokes that never fail to disappoint, the Hackney lad needs to get off Twitter fast. He's the equivalent of the embarrassing dad who rarely has something important or funny to say outside of his line of work, but unfortunately that doesn't stop him from boring the rest of the Twitter world. The biggest problem is he thinks he's hilarious, so he relishes the chance to get into arguments with other celebrities on Twitter because he thinks people are rooting for him - they aren't. Many are laughing at him, not with him, but Lord sugar is so far oblivious to it, and carries on sending everyone to sleep with his drivel.
