20 Worst Things Peter Griffin Has Ever Done in Family Guy
Fictional television characters make plenty of bad decisions, but none can rival Family Guy’s Peter Griffin. The character — voiced by series creator Seth McFarlane — is a respectable family man, but he is always overenthusiastic and reckless. Part of this has to do with the fact that he has a low I.Q. In the Season 4 episode “Petarded,” in fact, it was discovered that he has an I.Q. of only 70. Peter is also known to have a short attention span and is easily influenced.
