Why this makes every nerd’s head explode in anger, or laughter:
1) Patrick Stewart (dude in pic) is from Star Trek.
3) Harry refers to Harry Potter.
4) Gandalf, from Lord of the Rings, played by Ian McKellen in the movie adaptation of the book. No that is not him without a beard. That is Patrick Stewart from Star Trek (see #1 above). [Edit: I apologize for the typo on Gandalf's name, it has been corrected.]
5) None of these things belong with the other. Unfortunately, geeks and nerds often dis each other over dumb things like whether or not Star Wars or Star Trek is better. I happen to love both. Somehow all these nerd likes and dislikes come together and they make some awesome nerdiness.
