Spoonfuls of sugar

Dick Van Dyke just can't give up the chimney-sweep business. The actor, who turns 90 this week, will host a broadcast of 1964's "Mary Poppins," the first network broadcast of the film in 13 years. Van Dyke's co-host will be Target's bull terrier mascot, Bullseye, who, we assume, will offer special insight about the family dog, Nana. 7 p.m. Saturday, KSTP, Ch. 5

You decorated my life

Genevieve Gorder, who learned everything she knows about home design by decorating the Christmas tree in her Minneapolis childhood time, once again serves as tour guide for a "White House Christmas 2015," a behind-the-scenes look at how Washington professionals make the holidays more presidential. 5 p.m. Sunday, HGTV

It's a miracle

A reader has sent me several e-mails over the past two weeks, frustrated over his inability to find the original "Miracle on 34th Street" on cable TV. Well, sir, merry Christmas. You can watch the 1947 classic from the comfort of your own hearth at home this weekend, or trek out to select theaters next weekend for special screenings. 6 and 8:15 p.m. Sunday, Sundance Channel
