Mr. Lawrence was the principal of Degrassi Junior High School. Joey Jeremiah and Yick Yu were frequent visitors to his office. He began every school day with a thought for the day, which usually included a pun. The voice was that of John Bertram. Mr. Lawrence was never seen during Degrassi Junior High but his voice was heard both over the PA system and coming from his office (which on the set was merely a crawlspace).
