Title text: Did you know they can actually physically throw you out of SIGGRAPH?
The expression "bear with me for a moment" usually implies that what you are talking about is not random—the connection is to be explained later. This is not the case in the comic: Cueball is showing random slides which have no connection to each other.
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.
- 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...
- If you keep saying "bear with me a moment" people will take a while to figure out that you're just showing them random slides.
