Now, now... the people you're talking about are GUYS. Haven't you read Dave Barry's "Guide to Guys"?
"Shallow" is a GOOD thing -- it means our deepest thoughts and feelings are nevertheless close to the surface.
Think how much more frustrating guys would be to deal with, if we weren't transparent as glass. If guys could hide their feelings as well as women do, under multiple layers of denial and masquerade, the species would have died out long ago.
Celebrate shallowness!! :)
Like Jeff Foxworthy revealed about what guys are thinking, "I'd like a beer, and I'd like to see sumpthin naked."
Your tagline is AWESOME.
