The damned butter knife at family dinners.

One thing I DO dig about being a lefty is I still cut with my right hand. (Eating) Its funny to watch right handers switch their fork to the left hand (and back) so they can cut up their food. I think back in the day, a lefty was the one who set the standard for table settings. Fork(s) (and important meal utensils) are on the left hand side.
Awesomeness in a pseudo passive-aggressive kind of way
