"I'm sorry, I just didn't have time with all that seducing you wanted me to do... MOM!" Dramatic music played as she revealed the fact that the alien queen chick was her mother.
"Well, I shouldn't expect more from my hot but bone-idle... DAUGHTER!" Some equally dramatic music played as the alien queen chick revealed that the cute blonde babe was her daughter, even though everybody knew that already.
"I promise I'll do it right after I clean the V-skinning room... MOM!" The dramatic music, having lost its effect somewhat, played yet again as the show grossly underestimated the intelligence and/or attention span of its audience by revealing the exact same twist a third time.
"We get the idea!" shouted everyone. "Blow more stuff up and eat people and stuff!"
