Things that are so Far Fetched that they are annoying
1. In Be a Pal, the donkey in the living room. Really? That thing would have peed and crapped all over the floor. It's bad enough we are supposed to believe she got all those other props. but the Burro was just overkill
2. In Kleptomania at the end she brings a Baby Elephant out of the bedroom. Same problem as above except even more unbelievable.
In general for a housewife without a Charge-A-Plate Lucy does have quite a lot of access to costumes of every sort, even things that most likely would not be in Fred's Vaudeville Trunk...like in pioneer women they all had outfits and she had a bathtub on legs in the kitchen. In the one where she grew got the beard stuck, she had a harem girl outfit...but I digress....
