Wings

This comic references Titan, a moon of Saturn which has 14% of earth's gravity. Because the gravity is less, it takes less lift to fly on Titan.
Also, the main character uses hot glue on his wings, similar to how Icarus of Greek Mythology flew too close to the sun with wings made of wax. Just like Icarus, the character falls after subjected to high levels of heat. In the comic's case, the heat was applied by a heat lamp from xkcd's resident troublemaker "Black Hat".
Supported Features

Image meta text: I hear many of you finally have smooth Flash support, but me and my Intel card are still waiting on a kernel patch somewhere in the pipeline before we can watch Jon Stewart smoothly.
This comic is a reference to Linux builds adding suport and features that will not appeal to the majority of computer and Linux users. This example is full-featured flash support.
Asteriod

Image meta text: My Deep Impact/Little Prince crossover fanfic has been poorly received by the community.
Deep Impact is a motion picture from 1998 in which the protagonists have to blow up a asteroid that is headed to Earth. The Little Prince is a book by Antoine de Saint-Exupéry in which the Little Prince's home was on an asteroid.
In the comic, The Little Prince's asteriod home is headed towards Earth and the Deep Impact part of the fanfic lands the nuclear robot on The Little Prince's home.
