I couldn't find my Khruschev joke, but I found one that's funny:
'A flock of sheep approach the Finnish border in panic, pleading to be let in.
“Beria has ordered the arrest of all elephants,” they explain.
“But you’re not elephants,” reply the Finnish border guards in puzzlement.
“Yes, but try explaining that to Beria.”'
Proper tea is theft is one of my favourite jokes now!
