Cosby jumped the shark?

I also poised the jts question over at Friends, Roseanne, Sex And The City, Family Ties, Facts Of Life, Buffy The Vampire Slayer and Diff'rent Strokes

season 7 gets my vote, 4-6 weren't as strong as seasons 1-3, but Cosby was still must-see-tv. Season 7 was when the formula dried up

Season 7...The show became tired & boring:(

Anyway you vould revote? I accidently hit Day One but I meant to hit Season 4
