there r some friend jokes that u feel that only u and a handful of people really get. for ex: in the epsiode where joey gets the small chick and is petting it and chandler looks at him bemused and goes, " easy george", now that was a wicked joke but very few people actually got what chandler meant.( from the character of mildly retarded George, who crushed mice while petting it in Steinbecks classic-Of Mice and Men..
there are a lot of such undiscovered gems which escape friends fans radar, probabaly even mine too.
