I was out and about today, and I saw a bumper sticker "Obama '08!". The woman was loading her trunk up with groceries, so I said

"Ma'am, somebody played a joke on you. They stuck an Obama bumper sticker on your car. You might want to take that off!"

she said
"Oh no, I put that on there"

I said
"What are you on crack? MCCAIN Oh-EIGHT, COMMIE!"
