Answer the question at the end by quoting:

Walter Bruce Willis was born on March 19, 1955, in the town of Idar-Oberstein, West Germany. His father, David Willis, was an American soldier. His mother, Marlene, was German, born in Kassel. Willis is the oldest of four children with a sister named Florence and two brothers, Robert (who is deceased) and David.
Throughout his film career, Willis has depicted several military characters in films such as In Country, The Siege, Hart's War, Tears of the Sun, Grindhouse, and G.I. Joe: Retaliation. Growing up in a military family, Willis has publicly sold Girl Scout cookies for the United States armed forces. In 2002, Willis's then 8-year-old daughter, Tallulah, suggested that he purchase Girl Scout cookies to send to troops. Willis purchased 12,000 boxes of cookies, and they were distributed to sailors aboard USS John F. Kennedy and other troops stationed throughout the Middle East at the time.  In 2003, Willis visited Iraq as part of the USO tour, singing to the troops with his band, The Accelerators. Willis considered joining the military to help fight the second Iraq war, but was deterred by his age. It was believed he offered $1 million to any noncombatant who turns in terrorist leaders Osama bin Laden, Ayman al-Zawahiri, or Abu Musab al-Zarqawi; in the June 2007 issue of Vanity Fair, however, he clarified that the statement was made hypothetically and not meant to be taken literally. Willis has also criticized the media for its coverage of the war, complaining that the press were more likely to focus on the negative aspects of the war:  I went to Iraq because what I saw when I was over there was soldiers--young kids for the most part--helping people in Iraq; helping getting the power turned back on, helping get hospitals open, helping get the water turned back on and you don't hear any of that on the news. You hear, 'X number of people were killed today,' which I think does a huge disservice. It's like spitting on these young men and women who are over there fighting to help this country.  Willis stated in 2005 that he wanted to "make a pro-war film in which American soldiers will be depicted as brave fighters for freedom and democracy." The film would follow members of Deuce Four, the 1st Battalion, 24th Infantry, who spent considerable time in Mosul and were decorated heavily for it. The film is to be based on the writings of blogger Michael Yon, a former United States Army Special Forces soldier who was embedded with Deuce Four and sent regular dispatches about their activities. Willis described the plot of the film as "these guys who do what they are asked for very little money to defend and fight for what they consider to be freedom."

What did she suggest?

Tallulah, suggested that he purchase Girl Scout cookies to send to troops. Willis purchased

IN: Slipknot is an American heavy metal band from Des Moines, Iowa. The band was formed in 1992 by percussionist Shawn Crahan, drummer Joey Jordison and bassist Paul Gray. After several lineup changes in its early years, the band settled on nine members for more than a decade: Corey Taylor, Mick Thomson, Jim Root, Paul Gray, Craig Jones, Sid Wilson, Shawn Crahan, Chris Fehn and Joey Jordison. Gray died on May 24, 2010, and was replaced during 2011-2014 by guitarist Donnie Steele.

Anticipation for Slipknot's second album was intense. In early 2001, the band began recording the second album at Sound City and Sound Image studios in Los Angeles. Around this time, conflicts arose between band members due to extensive touring and recording schedules. Recording of their second album ended in February 2001 and the band embarked on their Iowa World Tour. Entitled Iowa, Slipknot's second album - released on August 28, 2001 - peaked at number three on the Billboard charts and at number one in the UK. The album produced three singles; "The Heretic Anthem" (promotional single), "Left Behind", and "My Plague", which appeared on the soundtrack for the film Resident Evil. In 2002, Slipknot appeared in Rollerball (2002), performing "I Am Hated". The release and intense promotion of the album resulted in sold-out shows in large arenas in several countries.  In mid-2002, Slipknot went on hiatus because of internal conflicts, and band members focused on side projects. Vocalist Taylor and guitarist Root revived their band Stone Sour, drummer Jordison created Murderdolls with vocalist Wednesday 13, percussionist Crahan founded To My Surprise and DJ Wilson went solo as DJ Starscream. For a while, the future of Slipknot was uncertain and there was much speculation about whether there would be a third album, or if the split would become permanent. "I don't have a problem with anyone in Slipknot," Jordison protested. "I've seen comments from Corey saying there are things to be resolved, but I have no fucking idea what he's talking about."  Nonetheless, on November 22, 2002, Slipknot released their second DVD, Disasterpieces.

Is there other members that worked on side projects too?
