Jill finds Brad making out with his girlfriend in his room. When Jill asks Tim to have a man-to-man talk with Brad, Tim is a little reluctant to do it. Not because he doesn't feel Brad needs it, but because it's something he's never done before with a kid. Tool Time goes to sea in another on-location shoot, with Tim, Al and Heidi boarding the USS Constellation aircraft carrier as part of their salute to engines.
It's a battle of halloween pranks. First Tim scares Al, then Brad and Randy scare Jill, then a strange man shows up at the door asking to see the basement. Jill, Tim and Wilson tell the boys that years ago a man named Clifford Warren was accused of killing his brother, but because of his mental problems he was put in an insane hospital. Little do the boys know that it's a halloween prank. They invite Al to help them pull a prank on their own, but Al and Wilson pull a prank on the Taylors.
Heidi goes into labor en route to the Classic Car Man of the Year awards and Tim and Jill help deliver the baby, while receiving instructions from Wilson on the phone.
Everything goes well when Mark uses karate to save Randy from a bully, until the school newspaper gets hold of it. Wilson's cousins, the Beach Boys, come to visit.
Jill's worst fears come true when she predicts something bad will happen on the night brad is first driving. He gets into a small accident but little do they know the accident is alot more serious than he admits.
