If a kiss or two will 
keep my mission safe...
...إن كان أمان مهمّتي متوقّفًا على قبلة
Wenn ein kurzer Kuss die Mission rettet …
Si un beso salva la misión…
Si un beso salva la misión…
Un baiser n’est rien
pour assurer celle-ci.
Se un paio di baci è sufficiente 
a far filar liscia l'operazione...
Caso precise de um beijo ou outro
 para manter a missão a salvo...
Если один поцелуй
поможет мне с операцией…
