NEW ORLEANS (AP) — Elementary school students climbed over each other to press faces and hands to the classroom windows. Rapper Snoop Dogg was at their school!

In New Orleans for a concert, Dogg told students at a hastily scheduled assembly Thursday that his favorite school subject was math. School is important, he said.

Dogg, aka Cordozar Calvin Broadus Jr., briefly mentioned his scrapes with the law, saying he decided to do right after getting out of jail.
