 The slogan on the poster read "Die Welt zu Gast bei Freundinnen" (The world as guest with girlfriends), a pun on the slogan for that year's World Cup, "Die Welt zu Gast bei Freunden" (The world as guest with friends).The protesters compared the poster to the Jyllands-Posten Muhammad cartoons.In response to the protests, and threats of violence, which began on 21 April 2006, the owners blacked out the flags of Saudi Arabia and Iran (both of which include words from the Quran), though the flag of Tunisia (which does not show any scriptural text) was left alone.
