Four For Friday - Friday The 13th Bad Behavior

All of these have been in at least one of the Friday The 13th movies.

#1 - This long time television star that everyone ships in a relationship had his role greatly reduced after he hooked up with an actress that this producer wanted for himself. 

#2 - This actor/crazy talk show guest thought himself too big for one of the installments because he had just been cast in a huge franchise at the same time. He got knocked out by an actor who had enough.

#3 - This horror offspring got pregnant during the shoot of her installment, but didn't know who the father was and gave the baby up for adoption.

#4 - This actor has a log career. He actually was the lead in shows and movies back in the day. He has been banned from several cons because he grifts off women he meets at them and he is lucky he hasn't been arrested.
