LOL David is my clown. Leave it to him to come up with the strangest, funniest things.

Can't begin to tell you how to gleek on purpose, anymore than I can tell you how to roll your tongue. It just kinda happens. We put our tongue on the roof of our mouth, not flat, curl it like a wave inside your mouth and then contract your gleeker. Did it work?

I had to practice for a while before I could make it happen. Damned if I was gonna let that boy outdo me! hehehe He has, in many, many areas, though.
