Ehhh, not really. It's a thing that happens. Also, I hate having my own Essen stolen, so I actually kind of dislike seeing it happen unless there's some balance, a.k.a. Scooby's Essen gets taken sometimes, too.
I'm natural to that joke. First of all I should point out that I hate mean spirited jokes. So that takes away a point. But some TV shows know how to do it right there are very few but some do. Even through I'm not a Fan of the joke, And yeah at times it gets annoying and isn't really that funny. But they did so good for a mean spirited joke. I didn't hate Scooby for it, It was really short and it didn't really effect anything. So I guess I should give them that.
