Speaking to Howard Stern on SiriusXM's The Howard Stern Show, Shinoda explained that Linkin Park were invited to join Metallica on the 2003 leg of their North American Summer Sanitarium tour, on a bill which also featured Limp Bizkit, Deftones and Mudvayne.
While Metallica have a history of pranking their support acts – most famously hiring male strippers to add some spice to Queensrÿche's set on the Damaged Justice tour in 1989 – no-one has dared prank the headliners themselves. Well, until Linkin Park decided to add their own brand of mischief, that is.
"Their show was always so tough and dark, so we were like, 'What would be the least tough, least dark thing to do?'," says Shinoda. "We ended up going out with a picnic basket and little sandwiches and drinks and Chester [Bennington] had a skateboard and skated out on stage. They were playing Master of Puppets and we set up a picnic right above Lars.
"We had gotten the go-ahead from their head of security and he promised he wouldn't take us out," he adds. "The guys were laughing. It's weird to be able to say that we knew them just well enough to know James wasn't going to knock my teeth out."

Last week, Linkin Park released Lost, a previously unheard track from the 2003 Meteora sessions alongside an animated video.
Lost comes as part of a special 20th anniversary reissue of Meteora, which lands on April 7 in a wealth of new formats, including a Limited Edition Super Deluxe Box Set, 4 LP Deluxe Vinyl Box Set, 3-disc Deluxe CD and digital.
