Superman in the 60's tpb. One story has Superboy going back in time with the Kents. He refuses to help a man being victimized by pirates because it would mess with time. A few stories later, Superboy is at a President's Day celebration and decides to go back and save Lincoln. Not mentioning the ramifications once.
Another story has Superman marrying Lois and adopting Kara. Lois mopes throughout the story. She's stuck at home cleaning while Superman and Supergirl are off having adventures (Lois also had to quit her job). The end of the story has Kara being taken away by Children's Services and Superman chuckles.
WTF??
