Every time the ep. is on, I get right at the end - WHY was BJ so angry at Radar after Radar went back to the States (the ep. in which BJ and Klinger got drunk).

I cannot tell you how many times I have gotten in on the EXACT same point in the ep.!

BJ was angry because his wife Peg and daughter Erin met Radar at the airport in SanFrancisco. Peg tells BJ in a letter that when Erin saw Radar in his dress uniform, she called him "Daddy." While Peg found this amusing, BJ does not.
BJ really wasn't mad at Radar, he was just angry that his daughter is growing up back home and he's not there to see it.

BJ was such a whiner! I love the episode where Margaret puts him in his place by the pinball machine (I forget the name of the episode).

I agree. BJ really got bitter in many episodes, espacially with the "whoa is me, I miss my wife and daughter" stuff.

The episode we're talking about is "Period Of Adjustment," from season 8.

Actually I think it was called "The Days of Whine and Roses" 'cause all BJ does is gripe about how tough he has it all episode. :lol:
