Notes:

One example of breast expansion from popular media I could find in gif form. Occurs in the Family Guy episode "I Dream of Jesus," with the context being that Peter asked Jesus (who's visiting Quahog at the time) to make Lois' breasts bigger.

I get the feeling some of the artists on this show have a love for oversized knockers on Lois given she has also had her breasts enlarged two times following this episode (one which was natural expansion via milk due to not breast feeding Stewie for a few weeks, and one via a cutaway gag where her breast enhancement surgery is interfered with by Peter telling the doctor to give her breasts big enough that she can't fully button her blouse).
