My all time favorite was a quote for the late Louis Grizzard, the Georgia humorist who often wrote about his Lab, Catfish:
"Labs are retrievers. They will bring you something to throw, and if you don't throw it....they will eat it.
Another time he wrote, " Labs are the only creatures who can drool in slow motion."
After reading a thread on weird things Labs have eaten I created this axiom,
"If it can fit in a Lab's mouth, they will eat it. If it won't fit in their mouth, they will tear it up, then eat it. If they can't tear it up, they will go find something else to eat."
