What won't get done for a week when a county wins something.

[Billys Boots]

Longford - the unicorns won't be milked for a week.

The blinds will be left up in the Stadia da Luz clubhouse for a week. 

[Dag Dog]

Tipperary - There won't be a ham sandwich eaten or ball of tinfoil  recycled.
Kerry - There won't be a yank tourist ripped off.

[Tony Baloney]

Marty Morrissey famously said there won't be a cow milked for a week when Clare won the Munster football title 20 years ago.
Since there is no grazing land in Clare, it would have been business as usual.

What could be said when other counties win something? What activity won't get done for a week with the celebrations?

Dublin - There won't be a spoon burned for a week.
Monaghan - There won't be a drop of diesel laundered.
Donegal - There won't be a Honda Civic written off
Wexford - There won't be a strawberry picked
Louth - There won't be a cigarette smuggled
Kildare - There won't be a stable cleaned out
Roscommon - There won't be a sheep sheared
Antrim - There won't be a petrol bomb thrown
Any others?

Dont lump the rest of us in with the McCooey's

True.

Subaru jacket washed....

I'll leave the incest ones out

Just seeing this now. 

You are of course talking about the Dunloy/Armoy/Glenravel triangle with Loughgiel in the middle of it. Fellas around the coastal areas are renowned for their sartorial elegance.
