I created a script a while back that verified age by birth date and received an email from Larry Walters that I might be infringing on his patent! The script I used is the same type as on the 
http://www.budweiser.com site and has been around since the early '90's. Larry's script is here:

Tell me that his Trademarked Patent Pendind script hasn't been used/seen all over the net in the past? 
Has anyone seen recommendations from people in the industry for Larry Walters or just articles made by him to promote himself?  hhhhhmmmmm
