Dim Bulb Who: Dallas Cowboys receiver Dez Bryant What: Was escorted from NorthPark shopping center Saturday after swearing at security officers who told him and three friends to pull up their sagging trousers. Why it’s dim: Despite the failure in 2007 of a Dallas mayor’s attempt to pass an ordinance against sagging pants, the city is still no friend to the fashion statement. Cure: Keep your waistband above your crack, please.
