This weekend on TV: LEGO of Homer! 550th episode of 'The Simpsons' is a hoot!

The 550th episode of The Simpsons (Sunday, 7 p.m., Fox/Ch. 13) is one of the best in a long time. Homer wakes up to discover that everyone and everything in Springfield is made out of LEGO ... except when he slips back into regular animation.
