Mark Dempsey has no problem making a show of himself to support his beloved boys in blue ahead of their Croke Park showdown.
The 35-year-old father of two from Tallaght and his brother Gary spent more than a week painting the outside of his three-storey detached house in the Dublin colours.
And it didn't stop there.
About two dozen Dublin GAA football flags flutter in the breeze from every window of the house on Cushlawn Grove, but the piece de resistance is the BMW 520 parked out front that he had custom-painted in a "photographic image of Hill 16".
He festooned the house in a similar manner when Dublin took home the Sam Maguire cup in 2011 and he is hoping history will repeat itself on Sunday.
But even if it doesn't, he intends to keep his "house of blues" intact for a few weeks to show his support for the team even though "the mother is sick of the house being a landmark and everyone taking photos".
The house certainly stands out among the two dozen houses on the quiet cul-de-sac. But nobody, save for his mammy, minds it, he told the Irish Independent.
"The neighbours all love it. They're mad for it," he said.
His two sons, Luke (11), who plays for his local Thomas Davis club, and Jack (6), are also football mad and proud of their father's decorating skills.
His only worry now is securing sold-out tickets for the clash at Croker.
Despite attending most Dublin matches "religiously over the past 15 years", Mr Dempsey was in near-melt-down yesterday as he scrambled to get tickets.
But with a pair of tickets fetching thousands, the unemployed carpenter was praying for a miracle as he scoured every club for a possible line on a pair of tickets.
He even entered the Ulster Bank's 'Best GAA Home' competition for a chance to win tickets, but was gazumped by another fan.
Still, he promised his efforts decorating the house wouldn't be in vain if the Dubs won. "If we get back early enough, we'll be keeping the neighbours awake," he warned.
