A Florida high school principal finds a witty graduation address on the Internet, and delivers it as her own -- that gets journalists fired and sets a bad example for students.

In an interview on Thursday, (Principal Susan) Duval said she had come across the speech while doing research on the Internet but did not learn the name of the author.

"I was searching for material I could quote," Duval said. "I never even saw a Chicago Tribune column. ... It was certainly not my intent (to plagiarize)."

Duval also said she did not intend to claim authorship of the speech, even though she had introduced it as some of her "personal thoughts."

If a student used that lame excuse, they'd still deserve an "F".
