Sample? (may be NSFW)

Seriously, how could that semen sample possibly be accepted by the police?

:D - "We'd like to submit a semen sample to prove that my friend didn't do it."
:o - "Oh really? Cool! Well if you'll just go to our doct...."
:D - "Got a sample right here. *shakes a bottle*"
:o - "Great! You even brought your own bottle. Thanks!"
:D - "And these fingerprint samples taken by all four guys she accused should definitely prove that they weren't even in the room, ever."
:o - "Excellent! Uh...one of these looks like a child's prints."
:D - "I know, right? Ha. That's not even why his girlfriend calls him 'Tiny'."

Among all of the ludicrous, silly moments in this movie, the moment the cop told Candy that one of the dudes had submitted a semen sample was the one that made me roll my eyes the hardest. What's your favorite moment to hate about this bit o' fluff?
