3. Consuela
There's quite a few grating characters in Family Guy. Mort Goldman and his high-pitched voice, his creepy, nerdy son, Quagmire and his womanising... But one of my least favourite characters is Conseula. Consuela is the one-time maid of the Griffin family ('Dog Gone') and apparent full-time-cleaning-lady of Quahog who only serves to annoy and infuriate. In 'Dog Gone', she point-blank refuses to leave the Griffin home at the end of her shift if it's raining and, after being fired, still refuses to leave. She even kidnaps Stewie ('Stewie Goes for a Drive') at one stage and is shown to steal from him. All in all, she's a pretty terrible person, and an all-round humourless character, and I definitely wouldn't mind if she ended up under the wheels of a speeding car.
