Jay goes head-to-head on the drag strip against former NFL quarterback Terry Bradshaw; takes comic Billy Crystal for a drive in Muhammad Ali's old Alfa Romeo; and surprises golfer Bubba Watson with the KITT car from "Knight Rider."

Jay explores tiny cars and big machines; crushes things in a tank with Arnold Schwarzenegger; drives a dwarf replica car with Brad Garrett; tours Lane Motor Museum's wackiest micro cars; and looks at a Hennessey truck named for a dinosaur.
