Listen up, everyone! Guinness World Records has just launched the 57th edition of its best-selling book of unusual - and, frankly, sometimes unnecessary - global achievements. And this latest version includes recognition for some never-before-recorded accolades.
Among them? There's 86-year-old Johanna Quaas, a retired PE teacher from Germany, who - as you may be able to guess from her picture above - is thought to be the world's oldest gymnast. Way to go, Johanna! Remember, it's less than four years until Rio 2016.
Meanwhile, Egyptian-born Moustafa Ismail has been rightly applauded for having the largest biceps and triceps on the planet...
In case you were wondering, Moustafa's slightly unnerving guns measure an incredible 25.5in (around 65cm) in circumference.
And Zeus, a Great Dane from Michigan, US, is now officially the world's tallest dog...
His height? An amazing 44in (around 112cm) from foot to withers. (We're assuming someone's already double-checked he's not actually a horse.)
Other new records listed in the book include the world's lowest-ever car, the shortest bull and the heaviest sportswoman. Take a look at some of the latest amazing record-breakers, below:
