I took an Intro Psych class in college and on day one of class, the professor taught us the most important lesson in the field of psychology.... "Psychology is a SOFT SCIENCE. Human beings attempt to bring rational constants and scientifically deduced theories into the realm of free-will and choice that is the human mind and it simply CANNOT BE DONE!"

It will weigh less. at least some of the people will have the couth to wash their hands, and when the wash water dumps overboard, (at least in some aircraft) that water loss will reduce the weight of the aircraft.

Unless the drain mast heater is inop, allowing an ice ball to form and grow to enormous size, picking up additional moisture from the freezing rain you happen to be in.......:p

Awesome answers, guys!

What if I changed the question a little? Would the plane weigh less if people took a dump instead? bwahahahahaha.

Maybe I am too hard headed.

Questions like this sound way too much like "admit it, my pen1s is much larger than your pen1s. Admit it, or be passed over"

It is a bit like "one must wear a certain suit and tie to be hired here". I understand I need to wear a proper business suit since this IS a conservative industry, but my tie is my way of expressing myself in a conservative environment. I don't go for a Jerry Garcia at an interview (though he has produced some attractive ties), but I DO like to show my taste and personality. If that doesn't conform enough, I don't think I want to work there.

Vegetarians or meat eaters? High fat content of the meat causes "floaters".
Ok - I watch too much House.:)

I don't have those things so I wouldn't know how to answer an interviewer if asked. And as a lawyer, I certainly don't readily admit to anything. :o

+1. Some companies are more into conformist employees while others are more into real employees.
