According to Jim
9 pm/ET ABC
Last week, Jim's get-rich-quick scheme to cash in on America's Funniest Home Videos never took off, and with Christmas coming up, he's not sure how he'll earn enough money to buy presents for all five kids. So tonight, Jim ropes Andy into a Plan B that involves getting the twins cast in a film starring Steve Guttenberg (who plays himself), though the notion of their kids becoming movie stars is anything but a hit with Cheryl. — Joe Friedrich
