[Cueball is standing on a stage, pointing at a line graph using a pointer.] Cueball: That chart explained the quantum hall effect. Now, if you'll bear with me a moment, this next graph shows rainfall over the amazon basin... [Caption below the panel:] If you keep saying "bear with me for a moment" people will take a while to figure out that you're just showing them random slides.

In the context shown, the expression "bear with me for a moment" usually implies that two seemingly unrelated topics are in fact connected, and the connection is to be explained later. This is not the case in the comic: Cueball is in fact simply showing random slides that have no connection to each other. By using the phrase liberally and never actually explaining the links, it is suggested that a presenter can simply continue to show random slides for an extended period before anyone actually realizes what is going on.
The title text refers to SIGGRAPH , an annual computer graphics conference held since 1974. In 541: TED Talk , it is said that Randall has been banned from SIGGRAPH, and we can infer from this comic that he was physically thrown out of it. Another (very implausible) possibility is that Randall is making the joke that people who attend computer graphics conferences are stereotypically not very athletic, and therefore unlikely to be able to physically throw someone.
In addition, the fact that Cueball was attending SIGGRAPH is another joke: Neither the Quantum Hall effect, a concept in quantum mechanics, nor rainfall in the Amazon forest, have anything to do with SIGGRAPH's focus of computer graphics.
