Well, Lord willing you won't find this one lame and corny...
A jock and a geek are applying for the same job.
The boss said, "Boys, you need to take a test before you can get this job."
So they took the test and the next day they came back to see who the boss chose. "Well," he said, "Both of you got the same score except I'm going to choose the geek."
The jock complained, "Don't you think that's prejudice or something?"
"Well," the boss said, "Let me tell you what happened. Both of your papers were right all the way through until the last question came up, and the geek answered 'I don't know,' and then when I looked at your paper, you answered, 'Me either'.
Was that one so bad? :)
