Tom and Jerry

Nit-Witty Kitty (1950x15)

:

Tom is chasing Jerry as usual, with Mammy Two-Shoes cheering him on. But when she attempts to crush Jerry herself by whacking him with a broom, she accidentally whacks Tom on the head instead. This causes Tom to suffer a case of amnesia, and he begins to act like a mouse. So both Jerry and Mammy individually try to cure him.
