As a self declared hedonist/barbarian (choose one or both of those), my list of finger foods is rather long. It should go without saying that I revert to knife and fork in situatins where eating with the fingers would make others uncomfortable.
Southern Fried Chicken
Most parts of quail and partridge
Chicken legs after most of the meat has been cut off
French fries (or by whatever other name you care to call them)
Corn on the cob
Nearly all Northern Mexican food so long as it is served with tortillas
Jerked beef, pork or chicken
Spiced shrimps (New Orleans style)
The best parts of the lobster
Crabs of course
Clams and mussels
Many kinds of pancakes and fritters
Ta'amia, felafel and other bean cakes
Stuffed vine leaves
Nearly all Arab and Bedouin foods when dining with Arab and/or Bedouin hosts
As to the ultimate "finger food" - When chef Woutrous Lap was in charge of the kitchens at the Sheraton Hotel in Libraville in the Congo, a group of revolutionaries invaded the hotel. Each of the hotel employees was forced to sit at a small table in the lobby and seated at the same table with Lap was a guerrilla armed with a Russian AK47 rifle. Knowing that it is always best to try and get your captor to know you as an individual rather than as merely a hostage, Lap tried to make conversation with the armed African.
At first, the man would not say a word, but finally, after he learned that Lap was the hotel's chef, he started to talk about the dining habits of his own village, where it seemed he was also considered a master cook. It also turned out that cannibalism was an accepted way of life in the cook's village. This, of course made Lap a bit nervous but he relaxed when the man told him that he did not have to worry because "white men have a bitter taste". Later, after Lap had described some of the dishes he especially liked to cook, the man decided to share a secret with him and told him that most of the people in his village thought that one of the very best parts of a human is the fingers, "because they can be dried, tucked into the pocket and later make for such good nibbling". Although the incident ended happily when the revolutionaries left the hotel several hours later without harming anyone, Lap has not added this particular kind of finger food to his own repertoire of specialties.
