Don't you think American Dad as well as Family Guy have both succeeded in creating a magical character that is so good they don't seem to be able to do ANYTHING wrong? Stewie in Family Guy and Roger on the American Dad side? Because I think so, I think both those characters are magical in that way and very unique.
Yes we can be honest that this episode, 'Roger Needs Dick', is not exactly American Dads most 'high brow' episode ever. Even though Roger's persona's conflicting with each other definitely has it's moments... But man did I think it was funny! Using the seemingly endless possibilities of Roger's crazy character, this one is really fun! Just fun.
So yeah, I laughed out loud quite a bit at the silly but creative Dick-jokes and Roger being his usual insane self! And what on earth is wrong with that?
