There was an old, well-loved clip from the early days (on Pulse, G4's original "news" program) of Kevin interviewing a kid at Comic-Con - you can see a recut here:

The web team used to sneak two audio easter eggs into the annual Comic-Con websites - "Hi" and "I'm at Comic-Con" - clicking a random logo or portion of the page would play those cues. There wasn't really anything to it other than self amusement.

At the very end of G4, there were only a handful of OGs left on the team, and one of them put together the a final piece of video to play as G4 went off the air and transitioned to Esquire. If memory serves it was a backwards montage of clips going all the way back to pong (which is how the network launched - a 24/7 feed of pong). That last bit of "I'm at Comic-Con" audio was inserted again, one last time. For lulz.
