The REALLY important question:
Does a woman who lies about her weight suffer from mass delusion?

As it turns out, the answer is "yes" or "no".  It depends on your 
frame of reference and the definition you use.  Using the definition 
that weight is the force exerted by gravity, then one would presume 
at a point near the Earth - Moon L1 point, you would be very nearly 
weightless (there would be some unbalanced gravitational influence of 
the Sun most of the time, but you could move around and null that out
too...).
