It was a long time ago. Actually, in physics my buddies were both fat. I forgot about one because I know she's not that smart even though she was in physics (basically an honors class without being labelled that). The other one was a guy. Sometimes you have the fat nerd guy. In other classes I don't remember any, but I'm much more likely to remember the attractive girls and outgoing people rather than cows.  Online I have a friend who says some fat cow (I tried talking to but failed to generate any interest in) is really smart, but according to him, believing in liberal bullshit is "smart." So she probably isn't that smart.
