What's that stink? A terrible smell is hanging over parts of England and Wales and it's not your dad's socks.
Loads of people have reported a manure-like whiff in London, Kent, Hertfordshire, Berkshire, East Anglia and as far west as Devon.
Weather experts say the nasty aroma is down to strong winds carrying smell caused by farming and pollution in Northern Europe.
It's thought the pong could hang about until Monday. Yuck!
