The third fellow said, “I think it might be a Chemical Engineer, because of hormonal balances and metabolism.” The other three nodded their heads and said, “Yeah, could be.”
The fourth fellow snaps his fingers and shouts out, “I know, it HAD to have been a Civil engineer!” The other three ask “Why?”
“Well,” replied the fourth fellow, “who else would put a waste water drainage right through a recreational area?”
