There are way too many misses in on the field though. But the hits are always gold IMO. Prank callers are usually the hardest to find a genuine comedy aptitude though.
The greatest troll comedian of all time though, IMO is Phil Hendrie.
People may know him from his voice acting work- King of The Hill, Rick & Morty, F Is For Family, etc, but his bread and butter was "hosting" troll characters on his radio show, and then interacting with callers as both the character and himself.
