Former A&E personality Tony McCollister -- who is charged with raping a child and having sex with two dogs -- says he's not guilty by reason of insanity ... and he wants to get his head checked. McCollister is facing 26 felony charges related to sex with a minor under the age of 10, plus 4 misdemeanor counts of sexual conduct with an animal ... and on Thursday, he entered his plea and filed a motion asking the court to order an evaluation of his mental state at the time of the alleged crimes. In Ohio -- where McCollister is charged -- a defendant must prove they did not know right from wrong at the time of the crime to be considered not guilty by reason of insanity. In 2015, McCollister appeared on the short-lived A&E show "Neighbors with Benefits" about a group of swingers. Public scrutiny led to the show being axed after only 2 episodes.
