Dean Wallis (born 27 August 1969) is a former Australian rules footballer for the Essendon Football Club of the AFL.
Originally from Nhill, due to his physical style of play Wallis became known as one of the leagues toughest players. He won premierships with the club in 1993 and 2000, and played 127 VFL/AFL games in his 14 seasons with the Bombers.
After retiring as a player he became an assistant coach for the Bombers. He left the club after Matthew Knights was appointed as senior coach in 2008, and moved to the Fremantle Football Club as an assistant coach. At the conclusion of the 2010 AFL season, returned to Essendon as a development coach, following Knights' replacement as senior coach with James Hird.
In 2011, Wallis was suspended from coaching for 14 games and fined $7500 by the AFL for betting on league games in violation of anti-gambling rules.
He stuck that knife right into her gut
I want to tell you she was lucky with what she got
But what she got was not enough
She played around
Don't play around
I tried to tell her he was not so dumb
I tried to warn her there was something wrong
She wouldn't listen, she continued on
She played around
If you give your love to someone and someone treats you bad
If you give your love to someone and someone makes you mad
If you give your love to someone it can be so sad
Don't play around
Don't play around
He left her dying in the pool of blood
And she was crying oh my god oh my god
But she was no good, she was no good
She played around
Don't play around
She'd be laughing and dancing the night away
She'd be laughing and dancing with every man that came away
But as her life's blood slipped away
I thought I heard her say
Don't play around
