What has made him so happy you ask? Well, a fortuitous twist of fate has handed him the new-business opportunity of a lifetime on, of all nights, Halloween.
On 31 October, Wacl is holding its next dinner (and no, Diary's not going to indulge in any witches convention gags), with the speaker being none other than Sharrocks' wife, the presenter Fiona Bruce.
However, being a little nervous about having to speak in front of a packed room (it's not as if she addresses millions of people each day on TV), Bruce has requested that her husband is there to give her a hearty dose of moral support.
Reward for this selfless act is that Sharrocks will be sitting on the president's table - the president being MindShare's Ita Murphy - who has filled the rest of the vacant seats with her top clients.
