Шутка о том, как Венгрия объявляла войну США (во Второй Мировой).

There's the old joke about the Hungarian ambassador handing declaration of war to the US Secretary of State Cordell Hull:
Hull: "Why would the Republic of Hungary declare war against us?"
Ambassador: "We are a kingdom not a republic."
Hull: "Your king approved this?"
Ambassador: "We have no king, we are ruled by a regent, Admiral Horthy."
Hull: "You are ruled by your navy? How big is it?"
Ambassador: "We have no navy, we are a landlocked country."
Hull: "So why do you want to fight us, do you have territorial claim against the USA?"
Ambassador: "We have no claim against you, only against Romania."
Hull: "Are you also declaring war on Romania?"
Ambassador: "No, Romania is our ally."

Каждый день. 

Безудержное.

АвторA Russian guy after visiting Ukraine tells to his friends:

• They are very strange there, they have there a lot of places for smoking and in Kyiv, on main street Khreshchatyk they have very big Japanese-Italian shop. :-)

What does that mean? Ukrainian word “perukarnya" (barber shop) in Russian is assosiated with smoking, so the guy thought barbershop was place for smoking. And years ago there was on Khreshchatyk big shop “hudziki-tkanini”. First word sounds “Japanese” for Russians, though it means just buttons for cloth, and second word sounds “Italian" for them, though it means just materials for making cloth.

Ахах)

Вторую часть шутки понял, но перукарня с курением? Почему?

Наверное делали анекдот для англоговорящих и не додумались что русскоязычные тоже могут прочитать. 

Когда-то видел более удачный вариант: мол, в Киеве есть улица Лисёнка (Лисенка = Лысенко), магазин итальянского портного Тканини и дань уважения Фрейду - станция метро Либидская.
