I was also thinking maybe having the opening skit be a "Fake out" movie trailer artily parodying Endgame in which it's revealed that somehow and for some reason, Sparky and Charlie have been going around assassinating a bunch of different webcomic characters and had somehow managed to reduce the Tapas Population to half through their efforts. Forcing a group of other surfing webcomic characters (probably made from characters participating in this event like Alpha Alpaca, Other Flare, Summer, Rip, etc.) to try to sot them, only to pan out at the end to show Sparky and Charlie watching the trailer in the theater and saying "Hollywood's really scraping the bottom of the barrel for ideas, aren't they?"
Also we find a way to squeeze "Gangsta's Paradise" in there somewhere.
