The answers to last week's "Guess the Sci-Fi References" are as follows:
1: Martian Spaceships from "War of the Worlds" (frame 4, top right corner)
2: Marvin the Martian (frame 6)
3: Martian from "Mars Attacks!", hiding in a canal (frame 7)
4: Arnie ("Quaid", from "Total Recall") removing his disguise, as he did when he got his ass to Mars (frame 6)
5: The Vinyl Goddess from Mars (an ultra-cheesy but excellent platform game) (frame 6)
6: Backdrop = a NASA concept-painting of some Mars mission - probably Viking (frame 8)
7: A poster of the Vinyl Goddess again (frame 10)...
8: ...below it, a poster for the schlock movie called "Teenagers From Outer Space" (if you recognised this one, add two bonus points!)
9: The "Mars Attacks!" poster (frame 10)
All these relate to the final, poignant frame:
10: "Le souffle de Mars" - that's French for "March's souffle", indicating what this month's special is at a local French restaurant. Hee-hee, just kidding, it's really "The Breath of Mars", but "March's souffle" sounds so much funnier that I just had to put it in Noel's Mars memorabilia.
11: "War of the Worlds" poster to the extreme left
12: An "I Want To Believe" poster
13: "Leather Goddesses of Phobos" poster - a text adventure for the Commodore 64 which probably inspired "Vinyl Goddess"
14: A "Get Your Ass To Mars" poster (You didn't get that one, did you?)
15: Another "Mars" computer game poster (extreme right)
16: "Total Recall" poster (mostly hidden)
17: Some kind of "Pathfinder" replica
18: A National Geographic with the heading "Martian Fossils"!
19: A Dr. Who Comic, and other nondescript sci-fi comics
In the music:
20: Sound very similar to the "Star Wars" theme, it does! Hmmyes!
21: BONUS: At the end of the first verse, there's a brief melodic motif stolen from some sci-fi TV series, probably "Stargate" but I just can't remember.

Did you get them all? (Well I should hope not!)
