- In Preggers, when Terri is about to reveal her hysterical pregnancy to her sister, Kendra, the latter asks if the baby is black. This is a reference to Jessalyn Gilsig's role of Gina Russo from Ryan Murphy's previous show Nip/Tuck, where the child she supposedly conceived with Christian Troy ended up being black.
