Much to Riff Raff's dismay, his mother is coming to town to see the beautiful mansion he lives in. Riff Raff, in a frantic attempt to cover up his fib, disguises his friends as servants and sneaks into a fancy house when the real owners leave, but Riff Raff's plan backfires and his mother finds out the truth. However, she doesn't mind at all that he is a simple alley cat and not the wealthy son she had thought. (thetvdb.com)
