A well-endowed university student was always being teased by her sorority sisters for being a size 36DD. One night, at a fraternity party, a young man asked her what she would like to drink. "I'll have a diet soda, please," she replied. "Oh, you must be the double D," he said. Furious, the girl wondered which one of her so-called friends had divulged such personal information. "And just what do you mean by that?" she snapped. Confused by her angry response, the man stammered, "You know, the designated driver."
