There are two birthdays coming up for my friends. One is a wonderful young woman from Vladivostok and the other is a friend from college who is a Russian major. I would like to know how to write "Happy Birthday" and "The Cake is a Lie" on their respective cakes and my Russian skills are somewhere around 0 on a scale of 1-10. I'm absolutely clueless about grammar rules, but I think that it would translate to "Cake is Lie" or some such thing, and I'm not even sure if that phrase would make any sense whatsoever in Russian. Any help with these two phrases would be greatly appreciated.
спаси́бо!
