Japanese Slipper Cocktail

Is there a definitive set of cocktails that every bartender trader should know? I see a list of 65 "official" cocktail of the "International Bartenders Association. Would this list be sufficient? Many of these drinks do not seem very popular today. If you go for a job interview is supposed to know you drink a lot more like "surfer on acid" or "The Incredible Hulk" or "red-haired bitch" or "AK-47"?
