Kim and Craig are hired by Carter's Unique Employment Agency to perform at a birthday party. But Kim loses her voice that afternoon and won't be able to sing, so Lucy must take her place.

Mr. French takes a two-week vacation to the west with the others staying home. When Bill is called away to South America for work, the children end up flying out west to be with Mr. French. It makes his vacation more enjoyable.

Tim (Bill Bixby) falls for pretty female reporter Cynthia Parker (Nancy Rennick), but has no idea what Cynthia likes in a man. Thus, Tim asks Martin (Ray Walston) to read the girl's mind--and as result, Martin finds out that in the long run, Tim and Cynthia would be poorly matched. Using every Martian power at his disposal, Martin endeavors to link Cynthia up with her "ideal" mate Bill (Robert Colbert), and to take care of Tim as well. (This episode was originally slated to air on November 24, 1963, but was rescheduled because of the JFK assassination).

Viv comes to visit and wants to take Lucy up on her suggestions for a date with her "good friend" Lawrence Welk. Lucy doesn't want to let Viv know that she was fibbing, she gets Mary Jane to bring in a Lawrence Welk wax figure, so maybe she won't be able to tell the difference. Kim and Craig manage to get the real Lawrence Welk to pay a visit, causing a wonderful sensation in the Carter household!
