Paul, Warren and a few others were driving back from the store when they saw a group of McCain supporters waving signs on the side of the road. One of them was young (think twenties instead of the expected sixties of most Republicans), which surprised Paul. So, he leaned out to ask the guy what was up.
He had to shout, however, since they were on a busy road.
Paul shouted out of the car: You're so young! Why are you voting for McCain?
The young supporter shouts back: What? We can't hear you!
Paul: You're so young! Why are you voting for McCain?
Supporter: What? Can't hear you!
Paul: But I can hear you!
Paul: Is this some one way sound barrier?
