I like the Heineken one where there is some kind of disaster on the way and this couple is at the supermarket getting supplies and food. The woman is fighting people for everything to put in her cart and she meets her man at the counter and he has only a 6 pack.
She looks at him dumbfounded.
He's like "What? Oh right". Takes off and comes back with another 6 pack.
She looks at him stunned again and says..
"We're gonna die"
LOL
