In this very first episode of The Dick Van Dyke Show, little Richie Petrie (Larry Mathews) is a bit feverish, and his mom Laura (Mary Tyler Moore) doesn't want to leave him with a babysitter. But Laura's hubby Rob (Dick Van Dyke) insists that Laura accompany him to a party at the penthouse of Rob's boss, comedian Alan Brady (actually, the party is more of a command performance, since Rob and the rest of Alan's writing staff is expected to entertain). Much against her better judgment, Laura agrees to entrust Richie to the sitter, and off the Petries go to the party, where a good time is had by all -- except Laura, who is convinced that something terrible will happen at home. And when Rob and Laura return to their split-level in New Rochelle, a state of disarray and few drops of blood convince Laura that her worst fears have been realized...or have they?
