longest putt ever made?

I made a 96 footer once on a enormous green. That's the longest one I've ever made or seen made (during a round) in real life

What is currently the longest-known putt made on television is one of 206 feet holed by short-game guru Dave Pelz at Whistling Straits prior to the 2004 PGA Championship.

Pelz made the putt while filming a segment for The Golf Channel about the humongous greens at Whistling Straits and how they could lead to putts the length of which PGA Tour players had never before had to face.

So he demonstrated on the No. 18 green, dropping a ball at the front of the green and putting to a flagstick more than 70 yards away at the back of green. After what seemed like 30 seconds of rolling, the ball dropped into the cup. There was so much elevation change on the green, and Pelz was so far away down at the front of the green, that he wasn't even able to see the ball go in.

I went putt, putt, putt in the car for about 7 seconds until my wife had to roll down the window.
