Foo Fighters frontman Dave Grohl is known for his foul mouth, so when the Foo Fighters played the Grand Prix after-race concert in Abu Dhabi over the weekend, he needed a little help.

Dropping an f-bomb in public is punishable by up to a year in prison in the United Arab Emirates so Grohl stayed out of jail by printing out a “NO CURSING” sign that he taped to his mic stand.

Grohl was proud of himself exclaiming, “I think that’s the first time ever!” He also quipped that Taylor Hawkins “would have loved this.”

Speaking of Hawkins, Dave Grohl dedicated “Everlong” to the late drummer saying, “I had a dream about him last night that he was bald with a ponytail. I swear to god, I really did. I dream about him three times a week, but last night’s was good, because he had no hair and a ponytail.”
