Everyone always says Joe was the funniest, which I do agree with but I believe the reason why the show is not the same without him is because how he bridged all the jokers together. He was able to be the piece who tired them all together and without him it just doesn’t have the same feeling
Imagine the Inside The NBA crew missing one of them. The magic won't be there. That's how I feel with the Impractical Jokers. The magic isn't there anymore. It has to be the 4 of them.
