What's the joke here? Do you have any feelings about it?

So I guess next you'd want to ask yourself how you think the penguins on the ground feel. Maybe they're inspired that something that seems impossible was accomplished with such a basic premise. Or maybe the obviousness/simplicity of the advice in both cases works against itself somewhat because it invites a sort of "well, duh" response that disinclines them to really follow suit. Depends on the state of mind you're in when you look at it.
