Maggie's Crib is a Bart Simpson Comics story that appears in Bart Simpson #71.
Maggie and Homer clash over who gets to use the kiddie pool.
Maggie goes outside to have a dip in her kiddie pool, and is disappointed to find Homer already soaking in the pool drinking a Duff. A plan occurs to her, however. Maggie goes back into the house and to her room, then breaks a wheel off of a toy car. She then goes to the pool and tearfully shows Homer the broken car. Moved by Maggie's tears, Homer gets out of the pool, then goes into the house and down to the basement, where he glues the wheel back on. Homer goes back outside to return the repaired car to Maggie and realizes, to his annoyance, that he's been tricked when he sees Maggie sitting contentedly in the pool sailing a toy boat.
