Imagine being in an advertising agency, devising a campaign for Walkers Crisps entry into the Irish market at the turn of the millennium.
Your star man is Gary Lineker, a local boy from Leicester and one of England's greatest strikers, but you need someone else, someone that will pique the interest of your prospective audience.
Then you have a brain wave.
"What about Roy Keane dressed as a giant leprechaun?"
There's a reason you get the big bucks, that's the ingenuity they've been craving.

It's amazing that Roy Keane once agreed to do that advertisement, but thanks to Keane's St Patrick's Day post on Instagram, we've been reminded of one of advertising's finest hours.
It features Gary Lineker darting around a heaving Dublin on St Patrick's Day, remember when that was a thing?
Everyone's after his crisps, a granny giving him shamrocks, a young fella on a pole, a giant Roy Keane in a leprechaun suit.
It's a romp, watch the full thing below!
