I bet YOU wearing your special bib overalls while giving the man-talk, scares the hell out of them!
The banjo music in the background is a nice touch too ;D

My Dad taught me that if you want too impress a girl and win over her Dad, you insist on meeting him, even when the daughter is afraid of what he will say and do ;)
I'd walk up, introduce myself, shake his hand and look him in the eye.
When he asked what time I was bringing his daughter home, I say " What time do you want her home?" I'd also admit that there might be beer at the function, and that we might have a few. Then I'd say " I don't drive under the influence, can I call you IF we need a ride?
 Never failed me, I stayed friends with some of the Fathers long after I quit dating their daughters ;D
