6. Nui-Nui
Verniy's name is pronounced "buerunui" in Japanese because of the limitations in how Japanese pronounces vowels and consonants, so it could be shortened to "Nui" off of the back end. The two "Nui"s are differentiated by being in katakana (for a foreign word) as opposed to Shiranui's hiragana (for a Japanese word). See this post for the same joke given more context.
