Carrie is talking about being able to fit the furniture in the baby's room, after she says she picked up a few boxes from the supermarket, she says Shalmonie Cuitsis sends them congratulations. Shalmonie is a game Doug made up when pretending to read in the episode 8 in Season 1 "Educating Doug".
The picture that Doug brings to the high school reunion is a picture of Leah Remini from the magazine Stuff in real life. You can see it when Doug shows the picture to his friend at the reunion. Carrie Heffernan is hot, but was probably not on the cover of Stuff magazine.
