//I won't bore you with the rest of the verse. You probably won't recognize some of the names anyway. Ever hear of Lebbaeus?

Different writers give different lists, and this has led to endless research, tracking down just exactly who is whom. Here's the full collection, borrowed from the Skeptic's Annotated Bible, if you'd like to try your hand at this exercise.
