English teacher corrects graffiti

MILWAUKEE (AP) - A Milwaukee English teacher is fighting graffiti with a grammar lesson.

After someone spray painted a police call box in her neighborhood, Beth Biskobing posted fliers correcting the vandal's grammar.

The tagger had painted, "Where da bitches at?"

Biskobing's flier responds: "Hey, Tagger! We'd like you to work on your grammar, please! Your tag SHOULD read as follows: Where are the female dogs?"

She explains that using the verb "are" turns the fragment into a complete sentence. She says "the" and "da" are not interchangeable, and a sentence should not end with a preposition, such as "at."

Biskobing discussed the vandalism with her students and showed them her flier. One student says it's "so geeky that it's cool."
