Based on David after the dentist:
Chad after the dentist:
Am I alone in not getting this whole meme?
Chad sounds more like Uhnold after the dentist… heheheh… 
Pike, little kids, you have not? Understand, you do not? Mmm…
Pike, I am with you. I feel terrible for that kid. He is scared and confused…how is this funny?
Have either of you seen the Chad Vader series prior to this?
I was actually following Chad pretty early on (I think I first mentioned him in the blog and/or forums.) It’s the loopy kid thing I don’t get.
I think they thought it would be a fun thing to do with Chad, nothing more.
Don’t get me wrong…the Chad take on it is hysterical. It is the original that I don’t see the humor in. Making fun of the original: funny.
