Seriously, Why Does Anyone like Pennies?

Anyone that has to deal with pennies on a daily basis is probably a raving lunatic by now.  My brief dealings with these annoying little disks is enough to cause temporary insanity, and wonder what anybody sees in these worthless pieces of garbage.  Why, oh why, do we still have these stupid things?  When someone asks you how far it is from New York to Los Angeles, do you say "about 2500 miles" or do you say, "2576 miles, 83 feet and 4 inches"?  Seriously, using pennies is like saying the second option.  It's just way too much detail.  Way more than you could possibly ever need, and provides no additional benefit over the first option.  In fact the second option just serves to waste your time, sort of like the penny does now.  Rounding to larger denominations is a good thing.  Let's all start refusing to use or accept these worthless pieces of copper trash and move forward to the 21st century!
