Frink is a college professor at Springfield Heights Institute of Technology[9] and runs his own astronomical observatory.[10] He has an IQ of 197 — 199 before he sustained a concussion during the collapse of Springfield’s brief intellectual junta — and is a member of the Springfield chapter of Mensa.[11][12] Frink is generally very polite and friendly. He has a trademark mannerism of using Jerry Lewis-style gibberish when excited,[5][13][14] such as “HOYVIN-GLAVIN!” and “FLAVIN” and impulsively shouting other words that have no relevance to the situation at hand.
