Besides the neighbors in the ABC black and white episode "Instant Hate",who were pretty weird(mean one minute,nice the next),were there any other episodes where the neighbors were also weird?

Sudsy and his mom were pretty weird. Sudsy kept inviting himself to dinner and to spend the night.

Jean's parents were kind of weird but pretty entertaining in the Sunday Drive episode. It's funny when they spend most of the episode sitting in the Douglas' station wagon in the driveway, while the boys and Jean keep going back into the house to get sweaters, etc. They never did get to go on their Sunday drive.

In a color episode -- Ernie's new friend "Mike," who I think qualifies as being in the neighborhood, was weird: Breaking a glass bottle in the Douglas' back yard with a slingshot, and destroying one of their vases inside the house with a lit firecracker...!
