1x57 - Tom and Jerry

Muscles, Jerry's cat-curdling cousing, arrives to help get Tom under control. Muscles is a mean streets mouse, and more than a match for Tom. When his muscle building regime doesn't work, Tom calls in his alley cat friends, "Dirty Work, Inc." to rid the house of Muscles. But Muscles evicts the alley cats and Tom surrenders to the might of this mouse.
