Deep Thoughts: Is that wrong?

For those days when there is nothing better to do than to ponder through musings of a twisted mind.
***************************

An internet friend of mine sent me this joke......and it got me thinking.

**** Joke****
Barack Obama got out of the shower and was drying off when he looked in the mirror and noticed he was white from the neck up to the top of his head.

In sheer panic and fearing he was turning white he called his doctor and told him of his problem.

The doctor advised him to come to his office immediately. After an examination, the doctor mixed a concoction of brown liquid, gave it to Barack, and told him to drink it all.

Barack drank the concoction and replied, 'That tasted like bullcrap!'

The doctor replied, 'It was, you were a quart low.'
***********end of joke***********

So is that really racist being that nObama is half caucasian? I'm not sure wether to half laugh or half rebuke my internet friend. Then I had to think again .... Does it count that the friend is a African American? Or would it count that he was a Conservative African American.

Being PC is so freaking impossible.

Hmmmmmmmmmmmmmmmmm.
