For instance:
My roommate accidently poked his gums with something while eating causing it to bleed slightly. He came to me asking about it. I joking mentioned it might be gingivitis. I went into great detail about it, which scared the shit out of him. That was a mistake. He kept bugging me about it...constantly asking questions about gingivitis and wanting me to look it up on the net. I suggested he go get his teeth checked, if he was so paranoid about it.
To make a long story short, the fool is now obsessive/compulsive about his teeth. He brushes and flosses after EVERY tiny thing he eats or drinks. He goes through one of those super sized Listerine mouthwash bottles in a week. He constantly looks at his teeth in a mirror and pokes and prods them to see if any are loose. I've actually observed him doing that at least 5 or 6 times in a span of one hour.
And worst of all, he constantly looks at other peoples teeth and gums and comments to me on them. "Dude. Did you see her teeth?" or "Dude, his gum line is receding."
Sigh. I have created a paranoid monster. Oh well. At least I can make fun of him for it.
