Robot bartender - a joke

I got this joke in an email message the other day. I laughed out loud. Check it out.

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 proceeds to make conversation
about global warming factors, quantum physics and spirituality, bio
mimicry, environmental interconnectedness, string theory,
nano-technology, and sexual proclivities.

The customer is very impressed and thinks, "This is really cool." He
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 100." Immediately the robot starts talking,
but this time, about football, NASCAR, baseball, super models,
favorite fast foods, guns, and women's breasts.

Really impressed, the man leaves the bar and decides to give the robot
one more test. He heads out and returns, the robot serves him and
asks, "What's your IQ?"

The man replies, "ah, ah, 50, I think."

And the robot says... real slowly... "So............... ya
........gonna.....vote for . Bush ........ again?"
