A big and tall dutch guy who'll do anything to hump your sister. He's climing in your windows, he's snatching your people up, tryin' to play them, so you'll need to hide your sister and hide your friends, 'cause he's humpin' everybody out here.

The typical Mr. Sister brews his own beer and studies Industrial Economics and Management
Mr. Sister: How is your sister?
Mr. Sister: I won't say anything about Sissel's boobs, but if it runs in the family....
