Kevan is a civil engineer and project manager for our city's water department.
A coworker handed him an amended document and said "here's the new testament".
A senior engineer, who happens to be a practicing jew, piped up and said "What's this New Testament stuff? Everyone knows it's only the Old Testament and everything after is just an addendum!".
The original engineer responded "yes, but we all know that an addendum is to repair a fouled up document!"
Priceless.
