curiosity killed hazeldove

some things i've been pondering the last few days:
-are squirrels the color they are, so they are camoflaged with tree bark?
-why does the ringling bros. circus have to walk the elephants through the midtown tunnel when they can just drive them over one of the bridges?
-if you changed the address on a netflix pre-paid envelope would your letter be delivered to your destination? is that mail fraud?
