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!"
