Is it considered to be a diplomatic no-no?
When you look at the Democratic People's Republic of Korea's website and can't stop giggling over it? I particularly like the page with the pictures of Great Leader Ronald Reagan and Dear Leader G**rg* W B*sh on it; when I become a cruel, but insane, yes, quite insane my pretties!, leader of the New World Order, I shall have a webpage like this one.
Update: I have been informed that the pictures of Great Leader and Dear Leader are not actually the gipper and Maximum Leader Genius, but they are instead members of the batshit insane Kim family. British Railways and I both regret the mistake.
