Ask Metafilter has an awesomely nerdy thread on "Crimes committed by Ferris Bueller during his Day off." Here are a few of my favorites:

Violation of 720 ILCS 5/32-5.1: False Personation of a Peace Officer.

Odometer fraud (tampering): 49 U.S.C. § 32703(2)
Odometer fraud (conspiracy): 49 U.S.C. § 32703(4)

720 ILCS 5/Art. 16D - 3 - computer tampering (when he changes his attendance record).

720 ILCS 130/2a, contributing to the delinquency of children. Class A misdemeanor.

"I'm pretty sure the leopard-skin vest Ferris wears at one point is some sort of fashion crime."

And the best:

The Save Ferris campaign might be liable for soliciting under the 740 ILCS 128 Predator Accountability Act.

Read the whole list and learn from Ferris's shameful example!
