No Giggity, No Doubt - where Quagmire tries to be a father to his newly-discovered daughter.
This episode was honestly like a drama - not one single funny moment! Although Quagmire is a dislikeable and creepy character, the writers' attempts to change him completely was unrealistic in regard to his established personality.
The entire episode was pointless - like a bad idea that didn't work, but instead of scrapping it they'd obviously gone too far, and just continued on to its pointless conclusion.
Connie's Celica was the best episode from more recently, the others mostly just had the odd good segment, but this one was truly awful - worst episode ever. 1/10 really is all it's worth.
