This is Mark McLelland, a 20-year-old landscaper from Scotland who partied so hard over the weekend he woke up on Monday too hungover to go to work. Scots! They're just like us! So McLelland did what we've all had to do when faced with a crippling hangover: he called out sick with "the runs." This is TMI which normally would make it a foolproof excuse. But there was a hitch: this happened yesterday. Yesterday was Sunday.His boss caught his fail and had the perfect reply.Being a bloke with a sense of humour, McLelland tweeted a screenshot of the exchange:When u wake up thinking it's Monday morning and text your gaffer wanting a day aff 😂 pic.twitter.com/Z3UAah2AY9— Mark (@Mark_McLelland) February 5, 2017 "When u wake up thinking it's Monday morning and text your gaffer wanting a day aff," he wrote.McLelland's text to his boss reads: “Greig isit awryt if a can take a holiday the day mate av got the runs man." (Translation: Had too much chipotle. Can't make it to work.)His boss, known only as "Greig," had the perfect comeback: "1 – you need to come up with a better excuse than the runs, that’s the worst ever.2 – it’s Sunday ya fuckin weapon.”No translation needed. Whatever "ya fuckin weapon" means, it's not something you want your employer to call you.Luckily, his boss has a good sense of humour too. “I woke up thinking it was Monday and I couldn’t get out bed so the first thing that came to my mind was the runs," McLelland told The Sun. “I never expected that reply but we usually get on well in work so we both saw the funny side to it.”In other news: now we know some good Scottish slang. Now get out there and use it, ya fuckin weapons.
