This is a true Supercalifragilisticexpialidocious place... There's only one tong twister that could possibly give Mary Poppins a run for her money and it can be found in the name of the quaint Welsh village of "L l a n f a i r p w l l g w y n g y l l g o g e r y c h w y r n d r o b w l l l l a n t y s i l i o g o g o g o c h". The name translates to “Saint Mary’s Church in a hollow of white hazel near the rapid whirlpool of the Church of Saint Tysilio with a red cave” and is the longest in Europe. Now you try!
