"My normal approach is useless here", from xkcd.
I'd seen this posted on a bulletin board in the hallway here, but I didn't know this was the source.
By the way, I assume that whatever ♥ represents, it has units. Therefore you can't take its cosine, since you can only take the cosine of a unitless quantity; similarly for the Fourier transform. And yes, I am deliberately missing the point here.
