(Internal: Jon pricks finger to test blood sugar, then runs finger under cold water to staunch the bleeding)
Jon's Finger: Hey, Jon, I'm totally not bleeding anymore. Go ahead and touch things to your heart's content! You totally won't get blood all over anything you touch...because I'm totally not bleeding. See? No blood.
Jon's Finger: Sucker! I so was still bleeding! Now you've gotten blood all over everything you touched!
