RJ is a Family Guy character from Wisconsin, according to creator Seth MacFarlane.
He first appeared in "Boys Do Cry", where in an interview with Tom Tucker he claims that he once saw Bigfoot while attempting to make love with his girlfriend at the lake. However, due to the amount of mosquitoes in the area, his girlfriend said that "there was no way".
MacFarlane noted in the commentary for "Boys Do Cry" that RJ was a liked character but just couldn't fit into episodes well. While credited as being from Wisconsin, he is also claimed as both Canadian and as a "Yooper", which is someone from the Upper Peninsula of Michigan.
He proposes to his girlfriend Janine in "Follow the Money", who starts to agree due to his strong arm. But when he falls and shatters his arm, she says "no way." When he finds a dollar on the floor from a shattered tip jar, he tries to win her over with money, but looses it was Tomik and Bellgarde pass by on a motorcycle. However, at the end of the episode, Janine is seen with him while his arm is in a cast.
RJ is voiced by Mike Henry.
