I caught a classic bit of the Today programme this morning. They had Falim Khoury (the head barman at the Savoy Hotel) shaking cocktails for everyone, and it was fairly evident from the general level of merriment that a certain amount of actual drinking was going on. Poor Charlotte Green had to try to read the news with sounds of shaking cocktails in the background, and she got a serious case of the giggles. The cocktail in question was a 'Corpse Reviver' — she evidently needed an anti-corpse reviver to stop her corpsing. In the end, she had to wheeze, "Stop it, Jim!". I assume that he was making faces at her and making it even worse.
Even if you didn't start your celebrations quite that early, have a good time tonight, and I hope that you do a lot of giggling.
