Haha Loved your post. Not sure how many already answered correctly but will answer whatever I got.
(1) It's a serial killer in the town. He goes and ask everyone why. Why are we here? If he doesn't like the answer he kills you. What a natural killer he is.
(2) Looks like an octopus caught red handed manipulating science reporters that it is an Aileen. Now I know where that news comes from.

(4) That is when you unzip those jeams, but you see God's spies crawl around it and then close it, because you are somewhat conservative about this shit.

(5) Offering steak to a vegan!

(6) Not sure if that is two friends exchanging their video collection in back alley or just bacterial porn.

(7) I know this, this is voldemort getting a nose job.

(8) That looks like Christan Grey's collection from 50 shades of grey. I will just quitely chuckle in my head looking at those beads.

Ok tried my best to keep it as absurd as possible but can't resist asking.
(3) Guess that's some mutagen you poured onto your plant. Though AGT to AGC mutation won't change the amino acid in peptide chain but still you got a phenotype. Maybe that SNP was in promoter? Or am I on totally wrong track ?
