ok iv found quite a funny codec call and its when ur on shadow moses jsut before you go to rex's hanger snake and otacon will talk about how snake took donw the tank and attack chopper in one of those calls otacon will start complamenting him in a "weird way" by saying hes insane and a hardcore bad*** then he will say "ur....the s**t"
i apolgize for the language used there but there just quotes so i cant be in trouble can i?
anyway il keep a look out for funny codec calls in the future
