This week's Supreme Court ruling on student speech started to set some boundaries on what teens can and can't say on campus. For the record:

Can't: "Bong Hits 4 Jesus."

(According to the Supreme Court today) Can:

A seventh-grader from Vermont was suspended for wearing a shirt that bore images of cocaine and a martini glass—but also had messages calling President Bush a lying drunk driver who abused cocaine and marijuana, and the "chicken-hawk-in-chief" who was engaged in a "world domination tour."

It will be very curious to see what happens when Harper v. Poway Unified School District comes before the Supreme Court.
