I was yelling "That Veronica Vaughn is one sweet piece of ACE" at my wife then got into an argument about which movie that was from which led to V names and:
Billy Madison - Veronica Vaughn
Happy Gilmore - Virginia Venit
Waterboy - Vicki Vallencourt
Little Nicky - Valerie Veran
I'm sure I'm not the first to notice but as a huge fan of 2 to 4 out of 4 of these movies I couldn't believe I'd never realized it.
