There really must be a generation divide on the type of humor in these comics. It seems like if there's any comments on a comic, it's always some form of "I don't get it" or "why is this funny".

I find it really interesting.

Anyways, it's humorous because "new kid" usually means new to this school but in this case it's "brand new" like the kids just came off the assembly line or something.

“Brand sparkling new.” Took me a min too.
