Walk the (straight) line

Kyle: Dude, there is one thing you should never do to your girl!

Stan: ?

Kyle: Never, ever ask her if she's virgin.
And even if you somehow do that, never laugh at her if she says yes!

Stan: Jesus Virgin Christ!
Dude, every girl says she is virgin. What's the point of the question?

Kyle: Hmmm
I guess it's just like us guys, who are never "drunk."

Stan: No. This is different

Kyle: ??

Stan: You can't ask her to walk in a straight line to prove her virginity!

P.s.: never ask your girl if she's virgin, cuz as an aftermath, she will irrevocably bounce the question back to you. And then, if you say yes, you are no good, and if you say no, you are no good!
