I'm pretty sure it's Harry E. Butt -- not Howard.
And without question, a much better title for the article would be, "Tortillas cause Butt trouble."
Look out!
When I was a kid, the big joke was that Piggly Wiggly (another regional retailer) was going to merge with HEB and they were going to call it "Wiggly Butt". That one was a big hit with the fourth grade crowd.
HEB issued a non-mandatory recall on the tortillas at significant cost because they thought it was in the best interests of their business and their custormers. They're a very honest and well run organization.
