The advice Troy gives to Adam on how to pick up girls ("Be charming. Be polite. Lie, if need be.") is funny in and of itself, but its nothing compared to how Adam puts it into practice. And it works!
Miss Sweet: (disdainfully, after giving Adam the once-over) "Yes?"
Adam: "I was wondering if you could help me? I, um..."
Miss Sweet: (glares at him with even more disdain)
Adam: "...seem to have lost my Congressional Medal of Honor around here... somewhere."
Miss 'Sweet: (bursts into laughter) "Now, that's a great one!"
