8. Steve Urkel Family Matters
Although living with stereotypical nerd Steve Urkel would include the benefit of being able to take advantage of numerous devices like his time machine and his teleporter, he's so monumentally annoying that you'd probably be happy to remain time machine free just to avoid hearing his voice all the time. Steve Urkel is like an African-American Jar Jar Binks. His voice and laugh are incredibly irritating, he's extremely clumsy, and just looking at him is enough to make you want to punch him. Plus he's one of those sitcom characters with around half a dozen catchphrases. Which would cause any novelty value he has to wear out even faster. Access to his intelligence and technology would be useful and he'd probably be okay with paying the rent and utility bills on time but since he's so prone to breaking everything, having him as a housemate would cost you a fortune in replacing furniture and paying for builders. And, thanks to his voice and personality, you'd be desperately looking for someone to let your room out to within weeks of him moving in.
