One of the best moments could be when Joey takes the reader to one of his acting gigs. It gives the reader a chance to see his passion up close. Another great moment might be when they have a picnic in Central Park and Joey tells his hilarious stories, making the reader laugh uncontrollably. Also, the moment when Joey tries to cook for the reader but messes it up in a really cute way is also a memorable one in many fanfictions.
One popular trope is the 'fake dating' scenario. Joey might need a date for an event and asks the reader to pretend to be his girlfriend. This often leads to real feelings developing. Another is the 'roommate' trope, where they live together and slowly fall for each other. There's also the 'teaching Joey something new' trope, like the reader teaching him a new language or a new hobby, which creates a bond between them.
Yes, there are quite a few. You can find some on popular fanfiction websites. Just search for 'Joey Tribbiani and Rachel Green love' and you'll likely come across some interesting stories.
You can try websites like FanFiction.net or Archive of Our Own (AO3). They have a large collection of fanfictions, and you should be able to find some dedicated to Joey and Rachel's relationship.
A friendship moment could be when Rachel is having a bad day at work and Joey just shows up with a pizza and some goofy jokes to cheer her up. They sit on the couch, eat pizza, and Joey tells her all about his latest audition disasters, which makes Rachel laugh and forget about her own problems.
They could also be involved in a neighborhood event. Maybe they are both trying to raise money for a local cause. Joey could use his charm to attract donors, while Rachel uses her organizational skills. Along the way, they face challenges like not getting enough publicity for the event, but they work together to solve it and strengthen their friendship.
Joey could be an ordinary citizen who just happens to be in the wrong (or right) place at the wrong (or right) time and meets the Batfam. Maybe he's a journalist trying to get a scoop on the Batfam and ends up getting more than he bargained for.
Joey Bishop in this story is likely to be a character, perhaps named after the real - life Joey Bishop. He might be the main protagonist around whom the events in the 'Weed City' story revolve.
There could be social consequences. They might face judgment from their friends or the community they are in. Some might not approve of their relationship or the fact that they are having a child at a certain time.
