Bobs Burgers is such a great show and i guess you've followed the show for quite long.
Yes, I have seen every episode. Who is your favorite character on the show?
the Melchers kids made the show more awesome. especially when they visit their friend at Wafstaff. 
It is Belchers with a B. And they go to the school WaGstaff. They have a lot of friends at school.
sure, did you recall the scene where Bob and other tenant rebel against increment of house fee?
Yes, during that episode they all ended up having a water balloon fight where they turned against Fischoder (thats the lanlord).
exactly and that made it more interesting. Bob really deserve what he got.
Bob's wife was the one who convinced everyone to change their mind. Originally, all the tenants had to throw water balloons at Bob and their rent would go down, but instead they all turned against him and STILL got their rent decreased because he respected them for their unanimous decision..
sure, he has been the most active tenant in the house and didn't deserve to be thrown a water balloons.
All the tenants don't live together. Each of the families had their own property that they were fighting for.
