Quote from Adrian Monk in Mr. Monk and the Sleeping Suspect
Captain Stottlemeyer: What do you see? Adrian Monk: Oh, he's not the guy. He definitely knew his sister lived here. He was at a barbecue here two weeks ago. Captain Stottlemeyer: But the package was mailed to the old address. Adrian Monk: Right. And he said he tied the surfboard to the roof himself. Look at these knots. They're a mess. Crude, tangled. But the knot we saw inside, on the bomb, was a work of art. Captain Stottlemeyer: So the feds... Adrian Monk: Are barking up the wrong tree.
