Never appeal to a man's "better nature."  He may not have one.

Girls, like butterflies, need no excuse when the need  to flutter arises.

Zombies drool.  Zombies smell very bad.  Zombies are notorious for bad hair do's.  Zombies are self-centered and violent.  Trust me, when I tell you a zombie is one of the worse things you will ever encounter.  A zombie does not stagger or crawl but moves slowly because it's muscles and tendons are rotted away and attempts at quick locomotion would cause a zombie to come apart entirely.  The smallest actions often require supreme effort.  A zombie lurching awkwardly toward its target is tantamount to a person with a severe disability.  If a zombie is legless , it crawls like a nightmarish inchworm.  You must disarm the zombie.  Especially if he has a samurai sword or a nail gun.  Those things hurt  something awful.

There was a young fellow named Bliss
Whose sex life was strangely amiss,
For even with Venus
His recalcitrant penis
would never do better than

           Instant Karma - Avoid unnecessary pain

 A Vikki witticism.

The best way to look at sex is that it is one of the most wholesome, beautiful and natural experiences that money can buy.
