The German word "Achtung" translates into English as "attention" or "watch out". U2's sound engineer Joe O'Herlihy used the phrase "achtung baby" during recording, reportedly taking it from the Mel Brooks film The Producers. Near the end of the album sessions, the band decided to use it as the album title.

Blinded you lost your way
Through the side streets and the alleyway
Like a star exploding in the night
Falling to the city in broad daylight
An angel in Devil's shoes
Salvation in the blues
You never looked like an angel
Yeah yeah angel of Harlem

Bono's, the Edge's, and Mullen's involvement in a Charismatic Christian group in Dublin called the "Shalom Fellowship" led them to question the relationship between their religious faith and the lifestyle of a rock band. Bono and the Edge considered quitting U2 due to their perceived spiritual conflicts before deciding to leave Shalom instead.

Bono described Spider-Man: Turn Off the Dark as a "three-dimensional graphic novel" and "pop-art opera". He also described the production as "wrestling with the same stuff as Rilke, Blake, Wings of Desire, Roy Lichtenstein, and the Ramones." Plagued by technical problems (several actors were injured performing stunts), the production closed on January 4, 2014, at a massive financial loss.

In 1993, Naomi Campbell was engaged to U2 bassist Adam Clayton. Although they never made it to the altar, Naomi has nothing but good memories, according to an interview she gave to Ireland's Sunday Independent.

Ah, sister, I can't let you go
I'm like a preacher
Stealing hearts at a traveling show
For the love or money, money, money
Desire

Bono is the only person in the history of the world to be nominated for an Academy Award, a Nobel Prize, a Grammy and a Golden Globe.

According to a recent survey, U2's 1987 single "With Or Without You" is the seventh most requested song at funerals in the UK.

Homer's campaign for Sanitation Commissioner starts badly when he is taken backstage and beaten for interrupting U2's PopMart Tour concert, but things turn around when he thinks up the slogan: "Can't someone else do it?" Homer spreads his message to the town and promises expensive services such as round-the-clock garbage service and sanitation workers doing all possible cleaning, leading to his landslide victory in the election.

I want to run, I want to hide
I want to tear down the walls that hold me inside
I wanna reach out and touch the flame
Where the streets have no name
