According to Wiki Answers:
No one is sure where the name of this dish comes from. Some believe it is called drunken noodles because it's an excellent hangover cure. Others believe that it is so hot that the eater has to be drunk to be able to stand it, while some are sure that it's because one becomes drunk trying to drown out the heat with alcohol. Still others believe that the name comes from the wide assortment of ingredients the dish contains: The chef is drunk enough to throw in a bunch of vegetables and spices without thinking it over. The most probable explanation is that this is one of the only foods available on the streets of Thailand late at night and in the very early morning, the times when inebriated revelers are leaving places of celebration. It is very possible that the extremely "wobbly" noodles themselves give the dish its name.
No matter how the dish got its name, one certainly need not be drunk to enjoy the delicious Thai classic, especially chef Scott Truong's rendition. After all, Truong's drunken noodles are Pearl Cafe's best-selling dish.
