Video: What a guy

Whataburger was so impressed with Joseph Russell's filmed testimonial for his love for the A1 Thick & Hearty Burger, the burger joint is using him in three commercials and a radio ad.

His students at Plano East Senior High School, where the education research doctoral student teaches sociology, started a Twitter campaign to make him the official "what-a-guy."

"I think they want me to give them free hamburgers," he says.
