Loblaw Companies, Crumbs/Miettes
Aired only in Quebec, a young man sits on a crowded bus between an older man and woman as he eats cookies. The woman keeps looking at him and the man is nervously tapping his fingers on his knee.
The woman looks around until she can't stand it anymore and finally grabs the crumbs off the young man's knee. He looks over at her like she's crazy but does nothing.
Then the man on his left is also prepared to pounce on the crumbs remaining on the guy's left knee. The older man starts to touch his leg and the other fellow sternly says (in French), "Don't even think of it!" then forcefully clears his knees of the crumbs.
This ad handles the man and woman as nearly equal by the young man's reactions, though the joke remains slightly more with the man touching him than with the woman.
