Fred has his times but there are times where he'll fly off the handle too fast especially when Barney makes a joke and Fred'll tell him to get out (whether it was in the car or house) and I don't know how many times he's said Barney and him aren't friends anymore over certain things but Barney is almost always there when Fred needs him the most even though he had his times like with the golf trophy and all that but I feel Barney is a better friend than Fred.

Fred is a bit selfish and self-serving

^ I agree with that-short and sweet! Well Said!:)
