He held her tight, a foolish grin on his face.
He had to fight to keep the smile from turning into a foolish grin.
He wondered how foolish the grin was on his face.
He could not keep a foolish grin off his face.
You get that big foolish grin, and your ears turn red.
He realized there was a foolish grin on his face.
He had hair the color of straw and a foolish grin upon his face.
As she watched the smile broke into a wide and foolish grin.
He was standing in the door, a foolish grin on his face.
She couldn't even wipe the foolish grin from her face.
