Absolutely hilarious. Nothing is funnier, more original, or cutting edge than early Family Guy.
This show was WAY ahead of its time and didn't garner a big enough audience to stay on the air. Only from re-runs on Adult Swim did the campaign start to get it back on the air.
The rest is history and Seth MacFarlane has become a very famous, wealthy man. Nothing he's done, though, can top these early episodes. They're absolute gems.
