Thanksgiving Prayer

A 4-year-old boy was asked to pray before Thanksgiving dinner. The family members bowed their heads in expectation.
He began his prayer, thanking the Lord for all his friends, naming them one by one.
Then he thanked the Lord for Mommy, Daddy, brother, sister, Grandma, Grandpa, and all his aunts and uncles. Then he began to thank the Lord for the food. He gave thanks for the turkey, the dressing, the fruit salad, the cranberry sauce, the pies, the cakes, even the Cool Whip.
Then he paused, and everyone waited -- and waited.
After a long silence, the young fellow looked up at his mother and asked, "If I thank the Lord for the broccoli, won't he know that I'm lying?"
