With that mother from that 70's show voicing her resignation and her reasons, we see that Betty had a point.
1: He was doing some odd things with this Princess Diana lookalike secretary -- why is she looking for a midlife crisis car for him???
2: He blows Betty off on a birthay tradition for going to lunch for -- what was it 4 hours--- 7 hours???
3: She basically becomes Mother to the children (good god that cake was pathetic looking)
The pieace de resistence... he ended up marrying her!!!!!!!!!!!!!!!!!!!!!!
