Ending...Brian shouldn't have died!
You know the theory that Christianity would have never spread if Jesus had never been killed....Seeing as Brian was not a messiah, the ending would have been funnier and made more sense if Brian have been rescued from the crucifixion at the last moment (and he goes like, "NoNo please don't save me...Oh crap, now I can't have my own religion!" :D
