Quote from Robin in Symphony of Illumination
Lily: Okay, first on the registry: nipple butter. Robin: Uh-oh. Lily: As you breast-feed, your nipples stretch out, like, four inches and get all dry and cracked. The nipple butter stops the bleeding. Robin: [to Barney] My four-inch nipples are going to crack and bleed?! Barney: Yes, but while the baby is gnawing on your bleeding nips, look what she'll be wearing.
