Even though we are often expected to "overlook" obvious impossibilities, several things about this episode have always bugged me:

Where did Lucy get all of those children's toys? She's always broke. A two-wheeled bike for an infant? Then how did she get rid of the toys?

When Mrs. Benson states she is mixing a meatloaf, Lucy says "It smells good." My meatloaves don't usually give off an aroma until they are baking.

Lucy and two older friends were able to completely move and set up two complete apartments up and down stairs in less than a day. When I move I live out of boxes for weeks!

Then, when the movers switched the furniture back, everything was in place. What movers would hang pictures and arrange knick knacks?

One poster several months ago mentioned the layout of the Benson' s Apartment. The daughters bedroom was right off the bedroom of the parents. For Lucy and Ricky a bedroom for a little baby was just perfect but a older daughter??? Yeah the episode does have some Wonders??
