Haha- oh...
Not bad! I enjoyed the story being told as a past account by the main character, and his character was nice, vulnerable and appealing. The main joke, though, didn't really find me well. It was a very funny twist for the first few seconds, but past one sentence I didn't think it worked as well. I understood that that was obviously the way the book had told him to act, and that the only other way you could have done this was for the girl to be repulsed and offended; this also has its drawbacks - it would have worked better, but it is a common joke, and for that reason, yours was a nice twist. But still, not as funny as I'd hoped in the end.
