Kerfluffle or kerfuffle?

This was funny, although I wonder about his use of the word "kerfluffle." I immediately checked the online dictionary to find out this word's definition (because that's the type of guy I am ;) ), but the dictionary doesn't use that particular spelling. It does, however, have a definition for "kerfuffle." Do you even care? ;) Anyhoo, here's the joke; from TBogg:


A man enters a bar and orders a drink. The bar has a robot bartender. The robot serves him a perfectly prepared cocktail, and then asks him, "What's your IQ?" The man replies "150" and the robot makes conversation about global warming factors, quantum mechanics, spirituality, biomimicry, environmental interconnectedness, string theory, nano-technology, and sexual proclivities.

Very impressed, the customer thinks, "This is really cool," and decides to test the robot. He walks out of the bar, turns around, and comes back in for another drink. Again, the robot serves him the perfectly prepared drink and asks him, "What's your IQ?" The man responds, "about a 100." Immediately the robot starts talking, but this time about football, NASCAR, baseball, supermodels, favorite fast foods, guns, and women's breasts.

Really impressed, the man decides to give the robot one more test. He heads out the door and returns. The robot serves him and asks, "What's your IQ?" The man replies, "Er . . . 50 . . . I think." And the robot says... real slowly ..............

"So.............. ya gonna vote for Bush again?"
