Lisa proves to be very responsible when she starts babysitting various kids in Springfield- including one night babysitting Bart. Outraged, Bart fully intends to make the night a living Hell. But Lisa unintentionally makes him fall down the stairs, busting him up. She tries to get him to a doctor, in a wheelbarrow, and various adults see, thinking she was planning to drown Bart and Maggie in mud. So now the babysitting thing is done. Or is it...?
A good episode, sometimes a little boring, but not too much by any means. My Overall grade would be about a B+/A-
