All in the family

In a movie, the hero's maternal grandfather killed the hero's father. During the final battle, the hero shouts at his grandfather:

"You not only murdered my father, you also fathered my mother."

Mao and his comrades were playing hide-and-seek. He said "No peking, no peking". Hence, the name change to Beijing. 

Who nose the answer?

If you accidentally let one rip in public, but want to avoid suspicion, how will you throw people off the scent?
