They were called [bad word] Four.
 Always slipping through the back door
 When [bad word] ashore,
 Sneaking through their precious load, 
 Cheating customs in a speedboat. 

 When [bad word] in from far away,
 Oh, they never can stay. 
 They fly away to other skies
 With the sun in their eyes. 

 Make their entrance two by two
 Bringing us a thought that's so new,
 Whistling secret tunes 
 And smuggling through their precious smile,
 Breaking customs for a short while.
