I do know the truth and I have the guts to admit it! I have a lot of respect for possums, too. You know why..........they are one of God's little creatures. Most are smarter than humans!<quoted text>I think it means that Norton knows the truth, but doesn't have the guts to admit it.
Naw, that would mean I am putting Norton on a mental and moral level of a garbage-eating possum and I have a lot more respect for possums than that.
