This one ought to be closer than the Friends poll.
Which Seinfeld character was funnier?
In my book, these are two of the four funniest human characters in the history of television, so it pains me to pick against either of them. However, gun to my hed, if forced to pick, I have to go with: George.
Hawkeye PierceGroucho Marx as host of "You Bet Your Life"
Mr. Robinson (Mr. Robinson's neighborhood, Eddie Murphy)
Jack Tripper
Benny Hill (various, but all the same character)
There's your top 5. Don't see Seinfeld characters anywhere on that list.
