If you really want to go the Islamic route, none of this would've happened because Bob would've been allowed to beat Barb into submission. Bob and Barb wouldn't leave Chris to go out drinking because alcohol is haram. Chris would not be allowed to watch cartoons like The Adventures of American Rabbit and MLP. Instead he would spend his days memorizing the Qu'ran and Hadiths. Sonic and Pokemon not allowed because it's idol worship. No babysitter incident because Barb would be at home all the time. Bob would eventually just get Chris into an arranged marriage with Megan, who would be wearing niqab and be a good, submissive muslim wife. Being asexual only adds to the her value. Chris then marries the other galpals like Blanca and PandaHalo. They have 12 kids. Instead of hoarding cats, they have a menagerie of animals like sheep and donkeys. No financhu crisis because charging of interest is haram. Chris doesn't need a job because they have the animals and a small subsistence farm.
So yes, refusing to submit before Allah and accept Muhammad (PBUH) as His messenger is what led to Chris Chan. God is Great. Death to America. Death to Israel. Curse ye hama upon the Jews. Victory to Islam!
There is not God but Allah, and the Bear is His Prophet.
OK I'm gonna run with this. Realistically Chris will only have one wife. The Chandlers were secure but not wealthy enough for Chris to have three wives. Blanca and PandaHalo are not fucking real, and their actors live far away so they're not even an option. Chris would probably not be able to get married to Megan since her family would have someone better in mind. Sarah Hammer is right out.
Wallflower is a possibility, depending on what the families could arrange. The more difficult the daughter the more likely they'll foist her off on Chris. Basically you'd demand a high bride price from the Chandlers because Chris is not going to bring anything to the table for your family. If you have a lot of daughters to marry off you'd ask for a hefty sum and send your least-likely one to the Chandlers.
Hambeast's parents would be heavily lobbying the Chandlers for a marriage, however. They might reluctantly agree because in CWCistan David is still loyal to Bob and is already carrying on the Chandler name and they just might write off Chris with Hambeast as a dead branch.
Of course in CWCistan Chris might have never happened at all, since Barb might have been stoned to death for being a harlot before she even met Bob.
EDIT: To be more specific, in Islamic societies there are two kinds of bride price. Their is the Quranic "mahr", which belongs to the bride and can be thought of as alimony. It can be either given up front or deferred, usually a mixture of both. This is for the care of the bride. If a poor family just wants to stop having to pay for their daughter, mahr might be enough. It ensures that if the husband dies, divorces her unilaterally ("talaq"), or abuses her in the presence of enough male witnesses that she can request a divorce with cause ("tafriq"), she will still be taken care of. In the case of Chris they would probably demand that most of the mahr be given up front since Chris' earning potential is not great.
The other kind of bride price is paid to the family of the daughter. This has no Quranic name but is still generally accepted in Islamic societies and has local names in whatever the local language is. This price would be based on how good a bride the daughter is and how badly the family needed to offload the burden of their daughter. Marrying Megan off to Chris would have had a significant bride price in addition to a mahr, possibly one the Chandlers could not afford.
Basically the mahr is a given, and must be higher up front based on the prospects of the husband. The bride price is more of a free-market issue based on how much people are willing to pay and how advantageous socially the marriage is for the daughter's family. Since the Chandlers offer little social value, and Chris -- even a Chris made responsible by more strict upbringing -- has little potential for future income, a family would mostly offer a wife that had little bride price value and they just needed so secure a sufficient mahr for. Someone like Megan would require a large bride price in addition to a large up front mahr.
