This is one of those erasers-on-the-end-of-pencils ideas that you kick yourself for not thinking of first. As you've gleaned from the headline, some genius (or geniuses) has elided the stage name of America's most prominent indie comedian, Louis C.K. and the title of Calvin Klein' first unisex fragrance, CK One, to get Louis CK One. There's a quiet brilliance there. Let it sink in.
Now, an idea is only truly good if it compels itself toward execution. As you can see, Louis CK One has certainly done that, fostering a Tumblr filled with well-wrought fake magazine ads, billboards, and the like. Again, let your mind soak in the sweet juxtaposition of popular culture's fastest rising, self-effacing, sweaty, miserable writer/director/comic and the timeless, minimalist appeal of a scent that was once advertised by Kate Moss.
As for what exactly Louis CK One would smell like — aniseed and pizza grease? Citrus and flop sweat? Baby powder and righteous rage? Your guess is as good as ours. (Paste)
