I can't understand this kind of cold joke ~ ~

Most Japanese don't pronounce the sound "R", and they use the sound "L" instead when they speak English. It may be because there is no such sound in Japanese, so they misunderstand and mistake supplies for a surprise ... Haven't you noticed that Japanese singers can't pronounce that sound except those who grew up in English-speaking countries (such as Utoda)? There is a Japanese band called "GLAY", in fact, they mean "gray", but because the Japanese can't pronounce correctly, they simply changed "R" to "L"!
