As usual, CBS will be making only minor tweaks to its schedule in midseason. The network’s new mulch-ethnic family comedy series ¡Rob! starring Rob Schneider will air in the Thursday 8:30 PM slot beginning January 12. To make room, CBS just cut the order for Rules Of Engagement, which airs in the time period; Rules will return later in the spring following ¡Rob!’s eight-week run. Based on Schneider’s real-life experiences, ¡Rob! stars the actor as a lifelong bachelor who just married into a tight-knit Mexican-American family. (Thus the Spanish-style punctuation of the title) Meanwhile, CBS’ reality series Undercover Boss will return to Sundays, serving as a bridge between the two cycles of The Amazing Race at 8 PM. It premieres on January 15. No word yet when and where CBS’ midseason drama The 2-2 will air.
