After all, it's not as sexy as the neck, and not as cute as the nose. It's not an area that is likely to fill him with passion, pleasure, and lust. It's for this reason that the forehead kiss has a special sort of meaning. Escort in Bower
Enjoying "long walks on the beach" is a romantic activity stereotypically associated with dating; specifically, it is commonly listed as an interest in dating advertisements and, more recently, online dating profiles. It is likely that many people who list this in their profiles have never, in fact, taken a walk on a beach or may not live near enough to a beach for it to be a viable suggestion for a date. In this comic, Randall lists "long walks on the beach" as an interest on a dating profile. However, while a romantic walk might last for half an hour or an hour before, presumably, moving on towards another activity, Randall suggests he likes walks that last several hours or even overnight, suggesting potential mates bring a tent to camp out in.
