Phish are an American band.
When Jesse asked for a volunteer to guard Springfield's oldest redwood tree, he said that once you're up there, "you can't come down. Not for a Phish concert, not even for Burning Man".
They appeared at a rally to save medical marijuana where they played "Run Like an Antelope". They then stopped as they could smell marijuana smoke and they demanded to see the prescription of the person it belonged to before they continued playing. Hans Moleman showed them the prescription and Jon Fishman told Moleman that he was seriously ill. The band then continued to play before welcoming Homer onto the stage. Homer told everyone to vote to save medical marijuana on the seventh. However, Mike Gordon pointed out that was yesterday. Everyone then left the concert.
When Moe was driving down the pavement rather than the road, he hit several signs, including a "Phish Xing" sign. He then hit Trey Anastasio who was annoyed at Moe because they had put up a sign.
