The two characters have appeared in the following movies:
In Dogma, Ben Affleck's character Bartleby shouts "Schüller Bob! I'll get you for this, Schüller Bob!" as Silent Bob throws him off a train. According to Smith, Affleck ad-libbed this, under the theory that Silent Bob has been thwarting Bartleby throughout history, so Bartleby recognizes him, and shouts in German, because German is the language spoken in heaven. It says a great deal about Kevin Smith's directorial style that he left this in the film.
Actually "Aramaic" is supposedly spoken heaven. Not to say that Smith and Affleck didn't go through that thought process. In Dogma when Rufus Chris Rock falls from the sky at a rate one would think should liquefy a human. He shows the note Jesus left for him telling him when would die, is written in Aramaic. Although the note was likely written on earth while both of them were alive.
