Showed up on an episode of
The Simpsons, playing at the Hullabalooza music festival....
"Who is playing with the London Symphony Orchestra? Come on people, somebody ordered the London Symphony Orchestra... possibly while high. Cypress Hill, I'm looking in your direction..."
(Cypress Hill discusses this amongst themselves, then they teach the orchestra "Insane In The Brain" Later, Peter Frampton is pissed because they stole his orchestra.)
