I knew it Vaughn's having a hard time explaining how Syd can be pregnant with at least twins, and only one of the babies is his. I think it'll get even worse when one baby is born fair-haired with cream colored skin and the other one has dark hair and possibly olive skin.
"Well you see...Syd's always craved pizza while she was pregnant. So, it's only natural one of the babies turned out Italian."
