Ferris Bueller's Day Off (1986) Review
When Ferris Bueller (Matthew Broderick) wakes up, he knows that he doesn't want to go to school. He's ready to take a day off and stop to take a look around. If you don't, life just might pass you by. But in order to do that, he has to convince his parents that he's sick enough to stay home, but not sick enough to go to the doctor.
In order to do that, Ferris gives us his plan. He's going for the clammy hands. While he's bent over from coughing, he licks the palms, which gives them the wet feeling. He also gives us a point-by-point on-screen blow of why not to go for a fever (you might end up at the doctor's office). Which is a little odd, really, because the on-screen thing isn't used elsewhere. But it works, and his parents head to work and he has the day off. Now he just has to get through it.
