"The Road to Bali" has a few guys wearing Javanese keris. 
Two of the character's names are amusing. 
Ramayana --- actually the name for a Hindu epic. 500 to 100 BCE
Ken Arok ---  a fascinating character in ealry Javanese history
http://en.wikipedia.org/wiki/Ken_Arok
The latter is a wonderful story about a famous Javanese keris and Mpu  Gandring. Certainly read the part about the woman (Ken Dedes) Ken Arok  went for and where she kept a shining light. 
However these characters in the movie have absolutely nothing to do with their famous names. I just think it is very funny that someone decided to name two people in a Bob Hope / Bing Crosby / Dorothy Lamour movie.
