A woman was visiting the zoo when she passed two workmen that were crying.
“Why are you guys crying?” she asked.
One replied, “One of the elephants just died. “
“The big elephant must have been your favorite animal in the zoo?” she asked.
“No, Ma’am– love has nothing to do with it. The boss told us we have to dig the grave. “
