Cognitive dissonance is what happens when you pull a band-aid out of the box and find a stinkbug sitting on it (I swear they are EVERYWHERE), and your logic circuits take .3 seconds to retrieve the response: "Just a stinkbug, nothing to worry about", while your lizard-brain goes "OHMYGODITLOOKSLIKEASPIDERITSASPIDERAAAAAAHHHHHHRUNLIKEHELL!". And since you can't think two things at once and fight-or-flight beats logic every time, you flail and send the stupid bug flying into the sink before regaining control of yourself and calmly retreating to a bug-free location hoping no one saw you freak out.
Rick got LEGO sets for himself as an early xmas present; because they were buy one, get one half off like every year at Toys R Us. We spent all night after I got home from work sitting at the dining room table, constructing a really cool Jeep-like vehicle complete with working doors and steering, a full trailer and 4-wheeler. Nerd bonding is the best bonding!
