Babies Overnight (babiesovernight.com) is a website that is accessible through the Internet in Grand Theft Auto IV. The website is a reference to the Pets Overnight website from Grand Theft Auto III, as both sites have similar names, premises and taglines. As advertised on the radio, Babies Overnight is a service that allows a customer to pick out the style of baby he/she wants, and the baby will box-ship anywhere in Liberty City in a matter of hours. Also, if a customer is not satisfied with the baby they receive, they can order a new baby and simply dispose of the old one.
As a minor detail, in the part where the countries from Africa are listed, the one called Pambia does not exist. This might be a misspell of Zambia or possibly The Gambia, and possibly, given Rockstar's satiric humor, an intentional one. On the same list, the country Nambia appears. This one does not exist either but may likewise be an intentional misspelling of Namibia, a real-life country.
- A woman on the Fleeca radio advertisement indirectly mentions Babiesovernight.com when asked what she does with Fleeca card.
- The background music playing during the Babies Overnight radio advertisement is the same as the one used in the Koala advertisement in GTA: Liberty City Stories.
