He recorded a goal, an assist and a major fighting penalty in the same game, an achievement known as a "Gordie Howe hat trick."

Parros had 183 penalty minutes during the 2007–08 season, at the conclusion of which the Ducks would be eliminated in the first round of their Stanley Cup defense by the Dallas Stars.

After the better part of 6 seasons with the Ducks, Parros left as a free agent and signed a two-year contract with the Florida Panthers on July 1, 2012.

[8] On July 5, 2013, after one season with the Panthers, Parros was traded to the Montreal Canadiens for Philippe Lefebvre and a 7th round draft pick in 2014.

[9] In the season opener against the Toronto Maple Leafs on October 1, 2013, Parros engaged in a fight with Colton Orr in the third period.

[11][12] After returning to play, Parros sustained a second concussion on December 14, 2013, following a fight with Eric Boulton during a game against the New York Islanders.

[18] The following day, Parros, as head of the Department of Player Safety, assessed a $5,000 fine to Wilson, the maximum allowable under the Collective Bargaining Agreement.

[19] The lack of suspension drew wide condemnation from coaches, from current and former players, including retired enforcers, as well as from fans and the media.

[20][21][22] The Rangers then released an unprecedented statement publicly condemning George Parros by name, accusing him of being "unfit," and calling for his removal.

[23] It was also reported that earlier in the year, Wilson nearly avoided what ultimately was a seven-game suspension for a hit to the head of Boston Bruins defenseman Brandon Carlo, who was hospitalized and missed nearly a month of action.

"[24] Parros is known for the large mustache that he often grows during the season, which he has said was inspired by a musician named Sean "Greazy" Bryan,[citation needed] known for his elaborate facial hair.

According to an OC Register article on January 28, 2007, while in college Parros had a fantasy hockey team called the All-Star Mustaches.

[25] "George Parros Mustaches" were also sold at the Anaheim Ducks team store inside the Honda Center, with the proceeds going to charity.

[26] Parros has a line of apparel called "Stache Gear" that benefits The Garth Brooks Teammates For Kids Foundation.

An employee of the Monarchs told Parros about "Locks of Love",[27] a charity organization that makes wigs for children who have lost their hair due to medical conditions.

[28] Parros is a fan of Swedish metal band Amon Amarth and is featured in their music video for the song "Raise Your Horns", of the 2016 album "Jomsviking".
