Anyway, one of these props was a giant hollow lemon meant to contain the band members as they rolled out onstage for their first encore. The lemon was chosen for two reasons: the first being a reference to the U2 song "Lemon," and the second being fuck you, thanks for all the money.
But you can't fault the unintentional result, which was magical: On more than one occasion, the lemon malfunctioned, leaving U2 helplessly trapped inside.
Thousands of people then just watched in stunned, awkward silence, because after two hours of cowboy suits and an inexplicable karaoke sing-along with the Edge, it was unclear whether clawing frantically at the walls of a giant piece of fruit was part of the show. In Norway, the band was able to climb out of the back of the lemon, but in Japan, they were sealed inside, presumably stuck listening to Bono's prerecorded voice reading passages from his own autobiography, as is customary in every vehicle he occupies.
When asked about it later in an interview, Bono said, "It was a beautiful thing, traveling in that lemon." This is perhaps less indicative of the crowd's response to the lemon and more related to the fact that the lemon was covered in mirrors.
"Shit, kill the spotlights -- the first two rows just caught on fire!"
