Dexter Colt is the main antagonist of The Simpsons episode, "The Dad Who Knew Too Little". He is a private detective hired by Homer to spy on Lisa and report his discoveries so Homer could appear to know facts about her life. However, Colt charges Homer $1000 for expanses, including a $40 steak, which would've been free had Colt eaten all of it, as well as silver bullets, because Colt initially suspected Lisa of being a werewolf. When Homer refused to pay, Colt framed Lisa of stealing all the animals of the Screaming Monkey Medical Research Center. However, he was arrested for the crime after Lisa temporarily blinded him with a laser pointer given by Bart. Colt made a cameo appearance in The Simpsons Movie as part of the mob. He is scheduled to reappear in Season 23. He was voiced by Hank Azaria.
