Dan Bergstein 

An acclaimed genius who rightfully describes the Twilight series characters (i.e. Pedweird is a pedophiliac stalker with control issues and Smelly Belly is a horny teenager who complains about her life and would rather have a controlling boyfriend than outdoor spaghetti) in a hilarious blog. An icon of Sparknotes. Also known as Lt. Lasermind.

Kid 1: Lt. Lasermind is a genius.
Kid 2: Pedweird and Smelly Belly are stupid, according to him.
Kid 1: I want to go onto Sparknotes and read his latest blog.
Kid 2: Dan Bergstein is the highlight of the entire site.
Kid 1: Let's have some outdoor spaghetti, too!

Bernsteined 

To totally destroy a sales cycle by forcefully interjecting into a corporate sale with malice against another salesman. Thus, killing any opportunity for future sales growth within a penetrated account or client portfolio.

I can't believe that "Eric" Bernsteined me out of a $1 million dollar deal out of spite!

Bergsteinn is a rare kind of tiger living in the woods south of Vejle. He hunts by traking down his pray with his highly developed sence of smell. The Bergsteinn then eats his pray raw and in one pice. His prais are most of the time fish, mouses and dead pidgens.

Sub. The Bergsteinn is hard to difine becouse they all look defriend but most of them are known for having huge heads and red hair.
