I think this was also a Jeep ad...it was for an SUV, at any rate.
Formally-dressed couple in said SUV come to a busy intersection. It is dark and raining and the intersection is full of angry people in cars honking and flashing their lights at a terrified stray dog that's in the middle of the intersection. The man in the SUV looks at his partner, then at a pair of ballet tickets on the dash, then back at his partner. Next scene shows the man running into the intersection, picking up the dog, and putting it into the back of the SUV. I cry every time I see it.
I also like the Zyrtec ads that show people allergic to their pets who decide to take Zyrtec instead of giving up their pet due to the allergy.
