If you thought Welsh rugby players had more brawn than Brains, you will be proved right... for one game at least.
Paris fashion: How the Welsh shirt will look in the Stade de France
A French ban on advertising alcohol posed a tricky problem for the clash in Paris this Saturday for SA Brain, the brewer which sponsors the Welsh team.
But the company has neatly sidestepped the rule by swapping the Brains logo on the front of the shirt for that equally prized rugby attribute: "Brawn".
Other Six Nations teams have had problems with the clampdown.
Scotland's whisky sponsor had to use just its initials on shirts at the Stade de France.
Brains decided to build on its "positive thinking" campaign, with the Welsh team on a high after two wins out of two so far.
Stewart Dobson, group marketing manager for Cardiff-based brewery, said: "We knew at the time of signing the contract last May that we'd have to face this task.
"So we looked at alternatives and everyone backed having some fun with it, including the players and the Welsh Rugby Union.
Cardiff style: Gavin Henson models the traditional look
"The Scottish team adapted their shirts just to the initials of their brand so I think the French are accustomed to people playing the game."
Fly-half Stephen Jones - who plays his club rugby in France for Montferrand - said it was a only a "slight change" in what would be "quite a low-key week" for the Welsh team before the game.
France v Wales will be on BBC One & Radio 4 Long Wave from 1545 GMT on Saturday.
