Professor Crawley

Professor Crawley is a bitter entomologist who appeared in The Jiminy Conjecture. He was then portrayed by comedian Lewis Black.

History
Professor Crawley mentions that he has studied insects since he was eight years old, earning him the school nickname "Creepy Crawley". He has 20 years of experience and a doctorate. He is divorced after his wife cheated on him with "a two-bit ornothologist who lives on a sailboat and likes to wear boot-cut jeans" while he was in the Bornean rainforest and discovered a new species of dung beetle. In The Jiminy Conjecture, Caltech has cut off the funding for his lab, forcing him to move in with his daughter in Oxnard, California. In the same episode, Sheldon and Howard ask him to identify a cricket they caught in order to settle a bet.
