Lucy and Lawrence Welk

S2 E18: 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!
