In her defense of using animals to test her cosmetics and trying to dispel the idea of rabbits being cute, Bella states very adamantly that rabbits are in the rodent family. They're not, they are lagomorphs and not related to rodents at all.
At the end of the episode Shirley and Paul are discussing their costumes. Shirley states she's dressed up as Diane Sawyer, a TV personality. In her role as Murphy Brown on the show Murphy Brown, Candace Bergen played a TV personality.
