Chernobyl Soup

A common name for cows milk in the late 80's on account of the fact that when the reactor 4 blew it's lid in 1986 and spewed all sorts of really nasty shite into the atmosphere, the prevailing weather at the time was unusually and unfortunately coming from the east and thus carried tons of highly toxic radiation 1500 miles west to the UK whereupon it pissed down onto our fields, the cows ate it, turned it into milk and then we poured it in out tea,

Customer: I've forgot my glasses mate, what's the Best Before date on this pint of Chernobyl Soup?
Grocer: 26th April 21986 mate. After that it starts to lose a bit of it's glow.
