"An example of systems analysis" joke

A social worker, a minister, and a systems analyst set out one day to
play a friendly game of golf. At the course, they found a long line
waiting to get to the first tee. They asked the party in front of
them what the problem was, and were told that a group of blind golfers
was on the course ahead of them.
The following conversation ensued:
Social Worker: Isn't it wonderful what handicapped people can do if
you just give them half a chance?
Minister: It certainly is, but those golfers aren't on the
course alone. The Lord helps those who help
themselves.
Systems Analyst: Yeah, it's neat all right, but why the hell can't they
play at night?
