Marty revisits the happy-go-lucky scene from before work and tells it as a series of calamities to Todd. The truth almost certainly lies closer to his description than what we would have seen earlier. Marty is an oblivious asshole and incredibly self-serving. While there is a lot of Perfect Strangers in the original concept (but definitely not this script) he is probably less self-serving than Cousin Larry.
I don’t think I wrote any kind of origin story for Todd and Marty. I’m not sure how long they’ve been friends, or why Todd continues to be Marty’s friend after being around him for more than a few minutes. It absolutely must have been a bond formed at a young age. That’s the only way someone could weather a person like Marty, I think. If as an adult you met a Marty, he’d be lucky if you walked away without kicking his ass after any encounter.
Marty himself, as we have seen, was violently thrown off a bus due to his obnoxious and intolerant ways in the opening pages. He very much deserved it, too.
