Okay, I was doing some thinking and decided to add on to this. Here's in full how I would have handled it. I'd have everything described above, but when they cut to a shot of the Mini-Mart, I would have Quagmire going "Ohgodohgod..." with Homer chasing him, but once Homer goes off-screen, he goes "Oooooh!" and pulls back in reverse and parks, jumps out of the truck and into the Mini-Mart for a brief second. We would hear Chris go "Thank you, come again!" and Homer would run out with a hotdog or a donut or something, jump back into the truck, pull out of the parking lot(Ramming into and denting the Mini-Mart sign in the process), scarf down his food and resume chasing Glen.
Then, at the end of the episode(Either during the credits or after the last scene with Jillian showing she's with West), they could cut to an apartment building with a caption saying "Meanwhile at an apartment somewhere in Springfield...". Then we'd cut to inside the building with Quagmire and Homer walking down the hallway. Quagmire could say he's sorry for trying to rape Marge earlier, but Homer then apoligizes for chasing him through several different states into Springfield. He would then tell Glen that since he wants sex, he set up a date with Marge's "two equally hot twin sisters"(He would give a sarcastic wink here) who are looking forward to a hot time with Quagmire. Quagmire would then dash into Patty and Selma's apartment exicted, and Homer would prop his ear to the door and say, "Hee hee hee, sucker. This oughta be good!" with a huge evil grin on his face. Glen would notice Patty and Selma(nude) and go "Ohgodohgodohgodohgodoh...what the hell, its better than nothing." and then we'd hear sounds of Patty and Selma giggling and Quagmire going "Giggity-giggity-giggity!" Homer's evil grin would turn into a look of sheer horror and he'd give a Homer scream and run down the hallway going "Ohgodohgodohgod!" and the episode would end there.
