Big-Lipped Alligator Moment: The first episode has the two boys explaining to a large crowd how they met Fleabag Monkeyface. One part of the flashback has them introducing the crowd to the Smugleys for absolutely no reason whatsoever (other than being a ham-handed way of introducing the characters to the audience). It wasn't even included within the flashback just for writing convenience; the scene actually cuts back to reality to have one of the boys explain to the crowd who these two people (who don't appear for the rest of the episode) are.
So Bad, It's Good: The show is so ludicrous and disgusting that you have to actually see it to believe it.
Special Effects Failure: Some have noticed that the red-headed girl is merely a clone of her brother with hair added. The Special Effects Failure lies in how one can actually see the line where the boy's hair ends where the girl's longer hair was added.
