post the nerdiest joke you know

[spock86]

Two physicists were riding in a hot air balloon and were blown off course sailing over a mountain trail. They were completely lost, when they spotted a jogger running on the trail and shouted "Can you tell us where we are?" After a few minutes, the jogger yelled back, "You're up in a balloon." One physicist turned to the other, "Just our luck to run into a mathematician". "How did you know he was a mathematician?" "Well, in the first place he took a long time to answer; second, his answer was 100% correct, and third, it was totally useless."
