Irish fastfood chain Supermac's is targeting McDonald's in a new kind of campaign.
It is putting adverts, on the side of trucks, outside restaurants of its US rival.
In a clear dig against the firm, the advert reads: "No clowning around, just great food!" - with an image of McDonald's mascot Ronald McDonald upside down in a rubbish bin.
This was spotted outside a McDonald's in Galway:
Supermac's has also posted the advert on their Facebook page.
The two companies have been locked in a legal battle over the right to use the 'Supermac's' name outside Ireland.
McDonald's claims having a 'Mac' competitor would create confusion for customers.
