Head of the Class

In the Season 2 episode "Don't Play With Matches," Dennis has created a computerized match-making program to connect his classmates with students from other schools. When it comes to Arvid, he has a difficult time finding the perfect match.

Arvid: Well how come she found someone so quickly?

Dennis: I'm more selective with you, Arvid. I mean, c'mon, there's not that many girls out there who like Mister Rogers.
