Ferris' Dad Spots Them

Ferris, Cameron, and Sloane are at a stoplight in a taxi, right next to Ferris' dad while he's reading a newspaper in another taxi. His dad glances at them once and when he looks at them again, Sloane takes Ferris's spot and wears sunglasses to disguise herself while Ferris and Cameron hide below their seat.
