When your spousematelovewife is going around the house, after watching American Idol, singing, "Dontcha wish your girlfriend was hot like me?", do not stop her and say, "Yes. I wish she was hot like you. It's something I'll have to talk to her about."
Eventually, she gets over it, but she's still staring at me out the corner of her eyes.
Smile. Type. Avoid. Repeat.
