Seinfeld during snl40 show made Williams a target...so how is Williams thereby perceived by you as “not fair game”...btw..I am no Williams defender, but ever since the mea culpa by williams...other allegations have come forth...by the same cosby technicality you are using, those newer Williams allegations are “unproven”...so not sure your consistency here
The Seinfeld quip was unscripted, and Variety reported that NBC execs were furious. The only other mention was from Jim Carrey on the red carpet, and the hosts were horrified and quickly cut away (see video here). So as I reiterate, Williams was NOT fair game, whereas Cosby was SCRIPTED in the show.
