Fall Out Boy have mocked fellow rockers PANIC! AT THE DISCO by bottling a pal during their set at Sunday's (26Aug07) Reading Festival in England. Last year (06), Panic! frontman Brendon Urie was left bloodied when a bottle hit him in the face, with missiles once again hurled at the band this year (07). But bassist Pete Wentz took the opportunity to make fun of the I Write Sins Not Tragedies stars' misfortunes - by inviting a pal to injure himself live on stage. He told the crowd, "People were asking us if we were nervous about playing Reading. We said no, because people here have always been really hospitable to us. "But we don't want be hit in the head with a bottle, because that sucks, so we brought our friend here, and he's going to break a real beer bottle over his head." The band's friend smashed a beer bottle onto his head, leaving him with a bloody nose.
