Yellow snow warning, really, on the BBC, does not say don't eat it.

Except it's a yellow warning for snow. Not a yellow snow warning, which isn't as snigger worthy.

 

[crystal ball]

From the great Frank Zappa

And she said, with a tear in her eye
Watch out where the huskies go,
And don't you eat that yellow snow
Watch out where the huskies go,
And don't you eat that yellow snow

 

[bernardgreen]

Don't worry, It will be all white on the night
