In New York City, we see a man walking around who is wearing a bathtub as a pair of shorts (as in, he’s not wearing a shirt, and he has a bathtub with water in it as his shorts, with his legs coming down through the bottom of the bathtub so he can walk around). People on the streets either notice him in an amused or irritated manner or ignore him. Then we see a woman walking around in New York City who is also wearing a bathtub as a pair of shorts. Then, from walking through the madding crowds of the New York streets, just by chance, we see the two bathtubs bonk into each other, and suddenly their eyes meet, and they have an instant love connection. Then we cut to the bathtub-wearing couple walking together in the countryside, where they find a lovely spot on a hill with a beautiful view, and they both sit down next to each other, forming the (ridiculous) Cialis logo of the two people sitting next to each other in separate bathtubs.
(I have thought for years now that this logo of two people outdoors, each soaking in a separate bathtub next to each other, is probably the silliest corporate identity image I’ve ever seen. And the above joke ad seeks to explain how it might have happened, when we all know it would never happen in any way whatsoever.)
