I quite like the simpsons Always gives me a giggle, but then im equally pleased with family guy or american dad, I find futurama a bit boring in that regard. Its nowhere near as "funny" giggle wise as simpsons.
With Simpsons Ill laugh out loud, with futurama is more of a "ha.. thats funny" in my head.
i agree with rich. the simpsons still makes me laugh. as for futurama and family guy etc, i think theyre funny but tbh i have no preference. theyre all as equally good as each other.
